(a) Failure of any party to perfect service of any notice or other paper hereunder shall not work dismissal; but the trial and appellate courts shall at any stage of the proceeding require that parties be served in such manner as will permit a just and expeditious determination of the appeal and shall, when necessary, grant such continuance as may be required under the circumstances.

(b) No appeal shall be dismissed or its validity affected for any cause nor shall consideration of any enumerated error be refused, except:

(1) For failure to file notice of appeal within the time required as provided in this article or within any extension of time granted hereunder;

(2) Where the decision or judgment is not then appealable; or

(3) Where the questions presented have become moot.

(c) No appeal shall be dismissed by the appellate court nor consideration of any error therein refused because of failure of any party to cause the transcript of evidence and proceedings to be filed within the time allowed by law or order of court; but the trial court may, after notice and opportunity for hearing, order that the appeal be dismissed where there has been an unreasonable delay in the filing of the transcript and it is shown that the delay was inexcusable and was caused by such party. In like manner, the trial court may order the appeal dismissed where there has been an unreasonable delay in the transmission of the record to the appellate court, and it is seen that the delay was inexcusable and was caused by the failure of a party to pay costs in the trial court or file an affidavit of indigence; provided, however, that no appeal shall be dismissed for failure to pay costs if costs are paid within 20 days (exclusive of Saturdays, Sundays, and legal holidays) of receipt by the appellant of notice, mailed by registered or certified mail or statutory overnight delivery, of the amount of costs.

(d) At any stage of the proceedings, either before or after argument, the court shall by order, either with or without motion, provide for all necessary amendments, require the trial court to make corrections in the record or transcript or certify what transpired below which does not appear from the record on appeal, require that additional portions of the record or transcript of proceedings be sent up, or require that a complete transcript of evidence and proceedings be prepared and sent up, or take any other action to perfect the appeal and record so that the appellate court can and will pass upon the appeal and not dismiss it. If an error appears in the notice of appeal, the court shall allow the notice of appeal to be amended at any time prior to judgment to perfect the appeal so that the appellate court can and will pass upon the appeal and not dismiss it.

(e) Dismissal of the appeal shall not affect the validity of the cross appeal where notice therefor has been filed within the time required for cross appeals and where the appellee would still stand to receive benefit or advantage by a decision of his cross appeal. (f) Where it is apparent from the notice of appeal, the record, the enumeration of errors, or any combination of the foregoing, what judgment or judgments were appealed from or what errors are sought to be asserted upon appeal, the appeal shall be considered in accordance therewith notwithstanding that the notice of appeal fails to specify definitely the judgment appealed from or that the enumeration of errors fails to enumerate clearly the errors sought to be reviewed. An appeal shall not be dismissed nor consideration thereof refused because of failure of the court reporter to file the transcript of evidence and proceedings within the time allowed by law or order of court unless it affirmatively appears from the record that the failure was caused by the appellant.
