FiveM developers have successfully addressed a major crash issue that was causing players to randomly disconnect from servers worldwide. The fix, implemented by contributor radium-cfx, tackles crashes related to streaming asset problems that affected both MLO and non-MLO areas.

The Problem

Community member raitrax reported the widespread issue on GitHub, describing how players on their server were experiencing random crashes throughout the day. The problem was characterized by:

  • Random crashes occurring anywhere on the map
  • Players crashing both inside and outside MLOs (Map Layout Objects)
  • Some players experiencing 1 crash per day, others over 10 times
  • The crash signature: Michigan-foxtrot-jig / GTA5_b3407.exe!sub_141533A9C (0x31f)

This issue was affecting normal roleplay activities and causing significant disruption to server communities.

The Technical Fix

Three weeks ago, radium-cfx implemented commit 96ef4ed which introduced a fix titled "tweak(gta/streaming): validate octant vertex count." The solution:

  • Validates octant vertex count during asset streaming
  • Mitigates crashes from assets with "broken" octant vertex data
  • Acts as a workaround rather than a complete fix
  • Prevents the immediate crash while maintaining functionality

Important Considerations

While the fix prevents the crashes, radium-cfx provided an important warning for server owners and developers:

"Just a heads-up: while the crash itself shouldn't happen anymore, it's still a good idea to re-export any affected assets using a newer version of the exporter you used. The fix we added may impact client performance otherwise."

What Server Owners Should Do

To ensure optimal performance following this fix:

  • Identify Affected Assets: Look for custom MLOs or streaming assets that may have been exported with older tools
  • Update Export Tools: Ensure you're using the latest versions of your asset exporters
  • Re-export Assets: Consider re-exporting problematic assets with updated tools
  • Monitor Performance: Keep an eye on client performance after the fix

Community Impact

This fix addresses one of the most frustrating issues facing FiveM players - random, unexplained crashes during normal gameplay. Server owners should notice:

  • Reduced player complaints about crashes
  • More stable player sessions
  • Improved overall server experience
  • Better player retention
