UEFN 41.20: Identical Launches Produce Inconsistent M-Menu Tabs and Map Markers

General Issues and Bug Reporting
, ,
1

Summary

In UEFN 41.20, repeated fresh launches of the same saved project snapshot produce inconsistent M-menu and map initialization.

Project settings:

  • Display Scoreboard = On
  • Display Overview Map = On
  • No HUD Controller is present
  • No Verse code hides or disables these UI elements

Observed results across three consecutive launches:

Launch 1:

  • Scoreboard and Overview appeared
  • Map markers were positioned incorrectly

Launch 2:

  • Scoreboard and Overview appeared
  • Map markers were correct

Launch 3:

  • Scoreboard and Overview were missing
  • Map markers were correct

The same saved snapshot and equivalent startup conditions were used for all three launches.

Log comparison showed:

  • The successful launch registered the Overview and Scoreboard UI extensions
  • The failed launch never received or registered those UI extensions
  • Two launches with nearly identical startup behavior produced different results
  • Incorrect map markers were associated with fallback map bounds instead of the project’s normal map bounds

The issue is intermittent and occurs without changing the project configuration between launches.

Steps to Reproduce

  1. Open a UEFN project in UEFN 41.20.

  2. Enable:

    • Display Scoreboard
    • Display Overview Map

  3. Confirm that no HUD Controller or Verse logic is hiding or disabling the Scoreboard, Overview, or M-menu.

  4. Save the project.

  5. Launch a fresh edit session and start the game.

  6. Open the Map key menu.

  7. Check whether the Scoreboard and Overview tabs are present.

  8. Check whether the objective markers are positioned correctly on the Map tab.

  9. End and fully disconnect the session.

  10. Repeat the fresh launch several times without changing or saving the project.

The issue is intermittent, so several launches may be required to reproduce each result.

Expected Result

Every launch should consistently display:

  • Scoreboard tab
  • Overview tab
  • Correctly positioned map markers

Because Display Scoreboard and Display Overview Map are enabled, these UI elements should register and appear on every launch without requiring any project changes.

Observed Result

Identical fresh launches of the same saved project revision produce different results.

Launch 1:

  • Scoreboard present
  • Overview present
  • Map markers incorrectly positioned

Launch 2:

  • Scoreboard present
  • Overview present
  • Map markers correctly positioned

Launch 3:

  • Scoreboard missing
  • Overview missing
  • Map markers correctly positioned

During the successful launches, the client registered the Overview and Scoreboard UI extensions.

During the failed launch:

  • No Overview UI-extension registration occurred
  • No Scoreboard UI-extension registration occurred

The project settings, saved revision, and general startup conditions were unchanged between launches.
