This appeal emerges from a procedural morass that began with appellant Charlotte Ann Plotner’s 1992 bankruptcy proceedings. As a threshold matter, we examine the effect of Saturdays, Sundays, and holidays on “compound” filing deadlines — i.e., filing deadlines consisting of an initial period subject to a finite extension. Concluding the appeal is timely, we determine, in light of the series of underlying suits brought in bankruptcy and district courts, whether the doctrine of res judica-ta bars the claims Plotner brings in the instant adversary proceeding. We then resolve whether or not the doctrine of res judicata applies in non-core bankruptcy proceedings. Joining the Second, Sixth, and Ninth Circuits, we conclude that it does. We further conclude that the necessary elements of res judicata are present, and the doctrine therefore bars Plotner’s claims. We exercise jurisdiction pursuant to 28 U.S.C. § 158(d) and affirm.
I
Although particular matters are hotly disputed, the underlying facts of this case are relatively straightforward. It is the procedural history that is unusual. Plot-ner, a real estate agent, filed for bankruptcy in 1992. Her primary asset was a parcel of land we will refer to as “the 1-40 property,” adjacent to an AT & T facility. Central Bank and defendant Brown Trust were mortgage-holders and secured creditors of the 1^40 property.
In 1993, the bankruptcy court approved a plan of reorganization for Plotner. Under this plan, through the “Plotner Land Trust Agreement” (PLTA), the land was transferred to a trust, under “Marketing Trustee” Gerald Gamble and “voting trustees” Plotner, Central Bank, and the Brown *1165 Trust. (I Appellant’s App. at 227-33; II Appellant’s App. at 272-92.) Central Bank later transferred its rights to the Brown Trust, giving the Browns majority control over the Plotner land trust. In April 1994, AT & T, through undisclosed intermediary Charles Green, made a $1.1 million offer for the property. The Brown Trust, opposed by Plotner, voted to approve the sale, and Gamble accepted the Green/AT & T offer on May 6,1994, immediately before the expiration of the offer. Green then transferred his interest to AT & T.
Alleging the existence of a superior oral offer, Plotner filed an Application for Rejection of Real Estate Contract in the bankruptcy court. This began the long series of litigation events enumerated below, eventually culminating in this appeal. Plotner now alleges an additional fact she claims to be dispositive of this appeal: that unbeknownst to her, AT & T released pollutants that contaminated her property, and failed to disclose the release to her or to the court. It is undisputed that Plotner learned of the pollution at some time no later than “some time in August, 1994.” (IV Appellant’s App. at 1134; V Appellant’s App. at 1196.)
Extensive litigation has followed the denial of Plotner’s motion to reject the real estate contract and the ensuing sale of the 1-40 property. There are no fewer than six previous court orders relevant to the disposition of this appeal, and we summarize them briefly below.
1. In re: Plotner, No. 92-17405-LN (Bankr.W.D. Okla. June 16, 1994) (“Plot-ner I ”)
The first written decision arose out of Plotner’s attempt to reject the sale of the land to Green. Judge Lindsey denied her application, specifically finding the sale of the property to Green consistent with the PLTA. Although Green’s offered price of $1.1 million was less than the “release price” specified in the agreement, the PLTA nevertheless authorized the sale of the property for less than the release price upon majority vote of the trustees. Finding such a vote had occurred and that the plan of reorganization had been substantially consummated, the bankruptcy court denied Plotner’s application.
2.
Plotner v. AT & T,
Plotner appealed the denial of her application to reject the land sale to the district court. Judge Alley, rejected the appeal as moot under the bankruptcy mootness doctrine because Plotner had failed to obtain a stay of the sale and AT & T had closed on the property. Plotner argued that an exception to the doctrine applied because AT & T was not a good faith purchaser, and that the district court could not make the initial determination of good faith and was required to remand to the bankruptcy court. Although not presented with Plot-ner’s pollution allegations, Judge Alley concluded the district court “is properly positioned for determining whether appel-lee acted in good faith” and found that AT & T’s use of an undisclosed intermediary did not deprive it of good faith purchaser status. (II Appellant’s App. at 513-14 (citing
Bleaufontaine, Inc. v. Roland Int’l (In re Bleaufontaine, Inc.),
3. Plotner v. AT & T Corp., No. CTV-95-50-R (W.D.Okla. July 30, 1996) (“Plot-ner II ”)
Plotner next filed suit not in bankruptcy court but rather in federal district court against AT & T, Gamble, and Green and his law partners in AT & T’s law firm McKinney, Stringer & Webster (collective *1166 ly “the law firm defendants”). Her civil complaint alleged various claims of fraud, negligence, and breach of fiduciary duty, including, by this time, the allegations of failure to disclose the release of pollutants. The district court dismissed for lack of jurisdiction. First, Judge Russell found a lack of diversity jurisdiction residence of both Plotner and the law firm defendants in Oklahoma, rejecting Plotner’s unsupported claims of New Mexico residency. Next, Judge Russell considered whether or not to exercise the power of a federal court to entertain an independent equitable action to attack a different federal court judgment pursuant to Fed.R.Civ.P. 60(b). He declined to do so, finding the exercise of Rule 60(b) ancillary jurisdiction unjustified, on grounds that Plotner failed to allege any affirmative misrepresentations or duty to disclose, failed to show that she or the bankruptcy estate suffered harm, and failed to show an inability to obtain an adequate remedy in the bankruptcy court. Finding neither diversity jurisdiction nor grounds for Rule 60(b) ancillary jurisdiction, and declining to exercise supplemental jurisdiction pursuant to 28 U.S.C. § 1367, the district court dismissed Plotner’s suit.

Plotner v. AT & T Corp.,
No. 96-6212,
Plotner appealed the jurisdictional ruling to us, and we affirmed that ruling in an unpublished order and judgment.
See id.,
5. Plotner v. AT & T Corp. (In re: Plotner), No. 92-17405-TS, Adv. No. 96-1220-TS (Bankr.W.D.Okla. Aug. 6, 1997) (“Plotner III”)
On June 21, 1996, prior to the resolution of
Plotner II,
Plotner filed an adversary proceeding in bankruptcy court against all the instant defendants, alleging fraud, tor-tious interference, and breach of fiduciary duty, likewise arising out of defendants’ conduct in connection with the sale of the 1-40 property.
(See
II Appellant’s App. at 520, 549-78.) Judge TeSelle issued findings of fact and conclusions of law dismissing Plotner’s claims on res judicata grounds, specifically finding the instant case to be a core bankruptcy proceeding and therefore subject to res judicata based on
Plotner I.
He found that
Plotner I
was a final judgment on the merits, involving the same parties (the law firm defendants in privity with AT & T because the suit involved their capacity as AT
&
T’s representative at the time of
Plotner I),
and the same issues, under the Tenth Circuit’s “transactional” approach to issue preclusion. Although Judge Alley dismissed
Plotner I
in part as moot, it is undisputed that Plotner failed to have the bankruptcy court order vacated pursuant to
United States v. Munsingwear, Inc.,
*1167 6. Plotner v. AT & T Corp., No. CIV-97-1832-M (W.D.Okla. Mar. 17, 1999) (“Plotner III Appeal”)
Plotner appealed Judge TeSelle’s order to the district court. The district court, Judge Miles-LaGrange, affirmed with only one significant difference in reasoning from that of the bankruptcy court. Avoiding the issue of whether Plotner III is a core proceeding for bankruptcy purposes, the district court adopted the reasoning of the Second, Ninth, and Sixth Circuits that “the doctrine of res judicata does apply to both core and non-core proceedings.” (VII Appellant’s App. at 1960) (citations omitted). Plotner now appeals.
II
During the pendency of this appeal, we requested supplemental briefing on whether the district court had jurisdiction in this case to hear Plotner’s appeal from the bankruptcy court ruling below. If the district court lacked jurisdiction, we necessarily would have no jurisdiction pursuant to 28 U.S.C. § 158(d), the district court’s order now being appealed would not serve as a valid “final decision[], judgment[], order[ ] ... or decreet ]” for us to review.
The issue is whether the district court lacked jurisdiction by virtue of Plotner’s failure to timely file her notice of appeal to the district court from the bankruptcy court’s judgment in Plotner III. Fed. R. Bankr.P. 8002(a), 11 U.S.C., provides for a ten-day period for filing a notice of appeal in the district court, subject to an extension under Fed. R. Bankr.P. 8002(c), 11 U.S.C., for a period “not [to] exceed 20 days.”
Plotner offers the following sequence of events by way of explanation that her appeal was timely. Judge TeSelle’s order in Plotner III was filed on August 6, 1997. On August 18, 1997, Plotner applied for extension of time to file a notice of appeal pursuant to Rule 8002(c). In an order filed August 21, 1997, Judge TeSelle ruled Plotner “should be granted an additional twenty (20) days in which to file her Notice of Appeal,” and ordered that Plotner’s time to file notice be “extended to Septem- ' ber 8, 1997.” Plotner filed her Notice of Appeal on September 8, 1997, therefore complying with the terms of Judge Te-Selle’s August 21,1997, order.
The bankruptcy court’s final order was entered August 6, 1997. Ten days from that date was August 16, a Saturday. 1 Plotner argues that therefore the ten-day period actually expired the following Monday, August 18, 1997. Twenty days from that date is Sunday, September 7. Plotner argues that therefore the final deadline for her to file within the twenty-day extension was Monday, September 8,1997 — the date she filed her notice of appeal.
Appellees, however, argue that examination of the foregoing sequence of events does not end the inquiry. In passing, they argue jurisdiction is improper because Plotner failed to include the order extending time to appeal in her appendix, and therefore it is not properly before the court. Although we “need not remedy any failure of counsel to provide an adequate appendix,” 10th Cir. R. 30.1(A)(3), (citing 10th Cir. R. 10.3(B)), we exercise our power to remedy the omission pursuant to Fed. R.App. P. 10(e)(2)(C).
Appellees also raise a substantive argument against the timeliness of Plotner’s notice of appeal to the district court. Ap-pellees correctly note thirty days (ten days plus a twenty-day extension) from August 6, 1997, is Friday, September 5, 1997, not September 8, 1997. We are aware of no bankruptcy rule permitting an extension of time longer than twenty days.
See Anderson v. Mouradick (In re Mouradick),
*1168 In general, if a filing deadline mandated by statute or rule falls on a weekend, the affected party has until the next working day to file. See Fed. R. Bankr.P. 9006(a), 11 U.S.C. (“In computing any period of time prescribed or allowed by these rules ... [t]he last day of the period so computed shall be included, unless it is a Saturday, a Sunday, or a legal holiday ... in which event the period runs until the end of the next day which is not one of the aforementioned days.”). This raises the question whether, under these circumstances, Rule 9002(a) applies twice, to extend both the initial ten-day period and the twenty-day extension, or whether it applies only once, to an overall thirty-day period derived from combining Rules 8002(a) and (c). We conclude that the district court’s implicit decision to apply the rule twice is correct. Any other result would effectively deprive parties of the benefit of Rule 9006(a) as to the initial ten-day filing period. Therefore, we agree with Plotner that her appeal to the district court was timely, and her appeal to us is proper under 28 U.S.C. § 168(d).
Ill
Insofar as this is a summary judgment motion, our usual summary judgment standard of review applies.
See
Fed.R.Civ.P. 66(c). However, the question of the application of res judicata to the facts, viewed in the light most favorable to Plotner, is a pure question of law subject to de novo review.
See State Bank of S. Utah v. Gledhill (In re Gledhill),
A. Elements of Res Judicata
We have characterized the elements of a res judicata defense as follows:
Res judicata requires the satisfaction of four elements: (1) the prior suit must have ended with a judgment on the merits; (2) the parties must be identical or in privity; (3) the suit must be based on the same cause of action; and (4) the plaintiff must have had a full and fair opportunity to litigate the claim in the prior suit.
Id.
at 1257 (citing
Murdock v. Ute Indian Tribe of Uintah & Ouray Reservation,
1. Judgment on the Merits
This case differs slightly from the conventional res judicata paradigm in that Judge Alley, in the
Plotner I
appeal, dismissed the appeal of Judge Lindsey’s order as moot, at least as to the sale itself, because Green and Gamble had already closed on the sale.
See Boullioun Aircraft Holding Co. v. Smith Management (In re Western Pac. Airlines, Inc.),
Plotner additionally argues that Plotner I does not represent a final judgment on the merits because her current claims would not have been “core proceedings” in the bankruptcy court. We address this issue in detail below in Section III.B, where we examine the applicability of the doctrine of res judicata to claims that would have been non-core proceedings if originally brought in bankruptcy court.
2. Identity or Privity of Parties
There is no meaningful dispute that the “identity of the parties” element is satisfied. Plotner, the Brown Trustees, Gamble, and Green were parties to
Plotner I.
AT
&
T appears on behalf of the same property interest as Green, creating privity between them.
See St. Louis Baptist Temple, Inc. v. FDIC,
3. Same Cause of Action
We have adopted the “transactional approach” of Restatement (Second) of Judgments § 24 in analyzing the “same cause of action” element of res judicata.
Petromanagement Corp. v. Acme-Thomas Joint Venture,
*1169 Under this approach, a cause of action includes all claims or legal theories of recovery that arise from the same transaction, event, or occurrence. All claims arising out of the transaction must therefore be presented in one suit or be barred from subsequent litigation.
*1170
It is noted that all claims relating to the alleged pollution of the property relate only to the failure to disclose such pollution in connection with the sale — the transaction at issue in
Plotner I.
Plotner asserts, for example, no personal injury claims from the pollution. For whatever reason, she did not assert the alleged pollution during
Plotner I,
despite the undisputed fact that she learned of it before Judge Alley’s order. Under our transactional approach, all her pollution claims relate back to “the same transaction, event, or occurrence,”
Nwosun,
4. Full and Fair Opportunity to Litigate
For appellees’ defense of res judicata to succeed, Plotner must have “had a full and fair opportunity to litigate the claim in the prior suit.”
Id.
(citation omitted).

“Essential to the application of the doctrine of res judicata is the principle that the previously unlitigated claim to be precluded could and should have been brought in the earlier litigation.”
D-1 Enters., Inc. v. Commercial State Bank,
Plotner’s principal argument against res judicata, if that doctrine is applicable to this proceeding, is that she could not have litigated her fraud claims effectively due to fraud on the court. She cites no authority for the proposition that fraud on the court is an authority to allow a
collateral
attack on a judgment — i.e., defeating the defense of res judicata — particularly considering that Fed.R.Civ.P. 60(b) provides for consideration of fraud on the court as grounds for
direct
attack— i.e., obtaining relief from the court that issued the original judgment.
See
Fed. R.Civ.P. 60(b)(3);
In re Gledhill,
*1171
Plotner also alleges that the bankruptcy court was not the appropriate place to litigate fraud, but the only authority she cites for this contention relates either to a procedural point,
see Robinson v. Tenantry (In re
Robinson),
With respect to Plotner’s contention that the Plotner I court lacked the power to grant damages relief for her claims, we note that Judge Alley, in refusing to dismiss as moot her claims against the Brown trustees, specifically contemplated and endorsed her ability to “pursue a claim for damages against the Browns.” (II Appellant’s App. at 516.)
Even if, viewing the facts in the light most favorable to Plotner, we conclude she lacked knowledge of facts that would have enabled her to litigate these particular claims at the time of the bankruptcy court’s
Plotner I
order, it is uncontested that she had knowledge of them during the pendency of the
Plotner I
appeal in the district court, a fact that we conclude is fatal to her claim that she had no full and fair opportunity to litigate. While a reviewing court, in this case the district court considering the
Plotner I
appeal, generally may not decide factual issues that were not addressed by the bankruptcy court,
see In re Robinson,
Plotner also contends that she “was prevented from presenting evidence which may have brought ... to light” facts regarding the Brown Trust’s knowledge of AT & T’s release of pollutants, presumably in support of her argument that Plotner I did not present a full and fair opportunity to litigate her claims. (Appellant’s Br. at 24.) However, the portions of the record cited in support of this proposition — chiefly excerpts from a June 13, 1994, hearing *1172 in Plotner I, as well as a September 1996 affidavit by alleged prospective buyer Warren Thomas — fail to reveal an effort by Plotner to introduce such evidence before the district court. Although it is true that Judge Lindsey, in the bankruptcy proceeding below in Plotner I, resolved Plotner’s motion without hearing Thomas’s testimony, review of the transcript portions cited indicates that Plotner sought to introduce that testimony only in support of a claim of a superior offer and never sought to introduce any evidence relating to claims of non-disclosure of contamination. Because the record belies'the assertion that she sought to introduce such evidence, we must necessarily conclude that any action by the court prevented her from doing so.
Moreover, insofar as Plotner implies, in her reply brief, that she was precluded from raising claims for trespass based on the pollution of her property, such an insinuation appears to be raised for the very first time in a reply brief on appeal of her third action arising out of these events. The fact that plaintiff chooses to advance, at this late date, a new theory of liability arising out of the same transaction does not suffice to obviate the application of the doctrine of res judicata.
See Clark,
5. Application of Res Judicata
Review of the numerous previous orders in this case compels a single conclusion: Neither a legal bar nor lack of knowledge precluded Plotner from pursuing her current claims before the bankruptcy or district court in Plotner I. She may have hoped for a more sympathetic forum by filing a separate civil action in the district court in Plotner II, but that court lacked original subject matter jurisdiction and declined to exercise its discretion to grant her Rule 60(b) relief pursuant to its ancillary jurisdiction over an independent equitable action attacking an earlier judgment. Thus, the doctrine of res judicata bars collateral attack on the judgment resolving claims that were or should have been brought in Plotner I.
B. Application of Res Judicata in Bankruptcy Proceedings
Plotner argues that the doctrine of res judicata is inapplicable because the instant action would have been a “non-core” action for purposes of the bankruptcy code if originally brought in bankruptcy court. Her argument is that because a bankruptcy court, without consent of the parties, cannot enter final orders in non-core proceedings, see 28 U.S.C. § 157(c), the doctrine of res judicata is inapplicable to later actions that would have been non-core proceedings in the bankruptcy court. As noted, the bankruptcy court in Plotner III found that the instant action is a core proceeding, whereas the district court declined to reach the action’s core or non-core status, instead concluding that the doctrine of res judicata applies to both classes of proceedings. After examining the applicable legal authorities, we adopt the approach of the district court.
The district courts (with power of referral to the bankruptcy courts) “have original and exclusive jurisdiction of all cases under title 11” (i.e. the bankruptcy code) and “original but not exclusive jurisdiction of all civil proceedings arising under title 11, or arising in or related to cases under title 11.” 28 U.S.C. § 1334(a), (b). Pursuant to referral under 28 U.S.C. § 157, bankruptcy courts have plenary jurisdiction over “core” bankruptcy proceedings,
see
28 U.S.C. § 157(b), but in “non-core” proceedings may only, absent consent of the parties,
see
28 U.S.C. § 157(c)(2), “submit proposed findings of fact and conclusions of law to the district court,” which then enters any final order or judgment, 28 U.S.C. § 157(c)(1).
See also Sender v. Buchanan (In re Hedged-Investments
Assocs.,
Inc.),
The Seventh and Fifth Circuits have held that non-core proceedings in bankruptcy cannot be given res judicata effect, because under 28 U.S.C. § 157 bankruptcy courts cannot hear non-core proceedings absent consent of the parties without being subject to de novo review by the district court.
See Barnett v. Stern,
The district court in this case, however, rejected the
Barnett
approach in favor of the approach adopted by the Ninth, Sixth, and Second Circuits.
See, e.g., In re Int’l Nutronics, Inc.,
Based on the policies underpinning the doctrine of res judicata, we agree with the reasoning of the Ninth Circuit in
International Nutronics. See Parklane Hosiery Co. v. Shore,
IV
Plotner additionally argues the district court erred in denying her motion under Fed.R.Civ.P. 60(b). We review a lower court’s grant or denial of a Rule 60(b) motion for abuse of discretion.
See In re Gledhill,
Although, as previously discussed, res judicata bars Plotner’s attempted collateral attack on
Plotner I,
that doctrine “does not apply to
direct
attacks on judgments.”
Id.
at 1082 (quoting Watts
v. Pinckney,
Rule 60(b) provides, in relevant part, that a court may relieve a party from a final judgment under, inter alia, the following circumstances:
(3) fraud [,] ... misrepresentation, or other misconduct of an adverse party ... (6) any other reason justifying relief from the operation of the judgment.
Fed.R.Civ.P. 60(b)(3), (6). Reason (3) has a one-year statute of limitations, whereas motions relying on reason (6) must merely be made within “a reasonable time.” Fed. R.CivJP. 60(b).
Plotner did not file within a year for Rule 60(b)(3) relief in
Plotner I.
She argues, however, that her district court fraud action
(Plotner II)
was filed within the relevant time period. Review of
Plotner II
confirms that although it sought Rule 60(b) relief, it was not filed in
Plotner I,
but rather as an “independent equitable action.” Fed.R.Civ.P. 60(b) specifically distinguishes the two: “This rule does not limit the power of a court to entertain an independent action to relieve a party from a judgment, order, or proceeding.” Refusal to recognize the distinction between a Rule 60(b) motion in the original proceeding and an independent equitable action, with its unique restrictions, would provide an undue incentive for forum-shopping to litigants dissatisfied with a judgment.
See Crosby,
As for Rule 60(b)(6), it may only be invoked as for causes
not
covered by another cause specifically enumerated in Rule 60(b)(l-5); otherwise, Rule 60(b)(6) would render the one-year limit applicable to Rule 60(b)(l-5) meaningless.
See Pioneer Inv. Servs. Co. v. Brunswick
Assocs.
Ltd. Partnership,
Because Rule 60(b) was not timely invoked, we come to the question of “independent action” relief from the judgment. Plotner has had a bite at this apple before. The district court rejected a materially
*1175
identical claim in
Plotner II,
and a panel of this court affirmed. Like the panel considering the appeal in
Plotner II,
we see no compelling reason for granting independent equitable relief.
See Plotner II,
y
In Plotner’s reply brief, she proffers a wide variety of new allegations and arguments, including assertions of criminality and unethical attorney behavior. Because these claims represent entirely new issues rather than responses to issues raised in appellees’ response briefs, we decline to address them under our general rule that we do not consider issues raised for the first time in a reply brief.
See Lyons v. Jefferson Bank & Trust,
VI
In short, this case represents precisely the sort of repetitive litigation that the doctrine of res judicata aims to prevent. Whatever the reasons, the record is clear that Plotner chose not to bring her pollution-related arguments in the initial Plot-ner I bankruptcy and district court proceedings, despite her prior knowledge of the underlying facts. Res judicata applies, and there is simply no exceptional reason to relieve her of the consequences of her prior litigation decisions. Nearly eight years after the initial bankruptcy proceedings in this case, it is high time for this matter to come to an end.
The judgment of the district court is AFFIRMED.
Notes
. We take judicial notice of the days of the week upon which the dates at issue fall.
. Because the parties have used the term "res judicata” throughout this litigation, we continue to employ that term, although we noted in
Yapp v. Excel Corp.,
. We have previously held, in an unpublished decision, that a bankruptcy court order "authorizing sale of real property ... is a final order” for purposes of 28 U.S.C. § 158(d), which governs the jurisdiction of the courts of appeals over appeals from “final decisions, judgments, orders and decrees” under 28 U.S.C. § 158(a), (b).
Bush v. United States Bankr. Ct. for District of Colo.,

. As discussed below,
Plotner II
was not a Rule 60(b)(2) or (3) motion challenging the

judgment within the same proceeding, but rather a new action commenced in district court seeking, in part, to invoke the court's ancillary jurisdiction to challenge the
Plotner I
judgment by means of an independent equitable action.
See Plotner II,
. As discussed below, because we agree with the district court that the core or non-core status of the instant proceeding is immaterial to the dispositive issue of res judicata, we decline to address the core/non-core distinction any further.
