Server crashing — GTA5_b3258.exe+7A3BBF / idaho-don-network — only stable when San Andreas mod map is disabled

Hey, my server has been crashing since yesterday with the following error.

Crash signature: GTA5_b3258.exe+7A3BBF
Legacy crash hash: idaho-don-network
Report ID: si-c334bd3d18fc4f9fa7cf541d24ca8108

Stack trace:

:warning: IMPORTANT — NOTHING WAS CHANGED:
The server was running perfectly fine. No updates, no new resources, no
configuration changes were made. It simply stopped working overnight,
out of nowhere.

:warning: KEY FINDING:
After isolating resources one by one, the ONLY way to stop the crash
is by disabling the San Andreas mod map resource. As soon as it is
enabled, the server crashes immediately with the above error.
This resource was working flawlessly before and nothing was touched.


What I’ve already tried:

  • Server restart
  • Fixed unrelated script errors showing in console
  • Isolated the issue by disabling resources one by one

This strongly suggests something changed on the FiveM/build side rather
than on our end. Could this be related to a recent build update, broken
octant data, or asset streaming changes in b3258?
Any help is appreciated.
