General Issues and Bug Reporting

Summary

Since the v41.20 update, players on my map Winter Rockets VS Cars (0105-1573-8859) are experiencing random client crashes where the entire Fortnite application completely closes.

This issue is clearly reflected in the map’s recent analytics following the update:

Playtime and Session Time: Both metrics have dropped significantly.
Bounce Rates: There is a noticeable spike across all platforms, with the exception of mobile.

After investigating the game logs:

CrashGUIDs:

  • UECC-Windows-B0AFC6A444F1B92B34E30488FD2A169D
  • UECC-Windows-D0C7BF274AD58EE1A39895982F30B4D8

The issue appears to happen when the full game ends and Fortnite resets the minigame for the next game.

The client crashes during the transition from PostRoundEnd to MinigamePostGameReset. During respawn, AFortPlayerControllerAthena::HasStreamingLevelsCompletedLoadingUnLoading() reports that the Winter_Rockets_VS_Cars Level Instance is still loaded around the time UWorldPartition::Uninitialize is running.

Immediately before the crash, the logs repeatedly report that it is not safe to respawn because the Level Instance is still loaded. The client then crashes with:

EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000648

Two separate crashes produced the same exception address and the same call stack.

More precise reproduction steps:

  1. Join island 0105-1573-8859.
  2. Play until the complete game finishes.
  3. Wait for the transition from the end-of-game screen into the next full game.
  4. During the minigame reset and player respawn process, the Fortnite client may completely close.
  5. This has reportedly affected PC and console players since v41.20.

Please correlate the two CrashGUIDs with the internal crash reports and symbolicate the call-stack addresses for build CL-55550516.
