Looks like this is the same bug as initially reported.

Didn't know dedicated server produced tracks. Please see attached.

e: looks like it took ~4 hours to trigger it.

2025-07-11 01:23:52.954 is miz load

2025-07-11 05:15:43.437 is crash pop-up

@BIGNEWY
This crash is still pretty much alive.

This crash with `edCore.dll` and `checkMissileThreat` is no longer related to the internal crash on our Kola server in this other forum:
 

 

Seems to trigger in our Pretense missions only.

Would sending you the .miz help? Not sure if you have one already but we all have a similar mission in this thread, if so please let me know how I could send it to you privately. Thank you.

Will join the topic. Also have 3 servers with modified Pretense and only one issue: same error as topic starter. Absolutely random and no chance to trace it.

[ChruutvoLuzi]

Issue is still persistent with todays update. Getting roughly the same amount of crashes, last was with 40 players connected and 4hours runtime.

something we noticed, our latest cold war server on germany does not crash at all so maybe some specific modern unit or model?
