Thanks for the report. Was that the only occurence of this crash or do you have details that would allow to reproduce this issue?

I was able to reproduce the crash on a test map with all mods disabled. It occurs every few minutes.

A crash report from my test installation should have been uploaded.

A save file is attached. If I load it, a crash often happens within a couple of minutes.

I am not able to reproduce any crashes from this save file which makes me suspect it may be an unreliable hardware on your end. Do you have log files from the other crashes to verify if they are crashing in the same exact place or if they are different places every time?

I have a 13900KS, so hardware issues are theoretically possible. However, it's otherwise 100% stable, including massive compile jobs. The system has always been running with Intels recommended power and current limits set (and not the mainboard default settings) and the RAM is clocked at standard JEDEC 4800 speed and not XMP.

The crashes occur in the same place, e.g. this is one from the test map that I attached:

1012.515 Error CrashHandler.cpp:190: Map tick at moment of crash: 67449

I made some changes to the belt layout and there hasn't been any crash for 25 hours.

I strongly suspect that there is some corner case bug with very specific thread timing that was triggered by my base; perhaps memory corruption because of an object lifetime issue.
