Thanks! I should be able to RMA it, I'll make a new post if I find Factorio specific problems with a new one.

Solved! It's a raptor lake defect. CPU has a fit every now and then. Fits exactly the description of the same problem anywhere I can read about it.

I have had it since jan24, so it probably was effected by it, as far as I remember, all 13th and 14th gen intel were effected.
I do have the latest firmware on the mobo (version from 6-12-2024)
I'll run prime95 once I'm home later, thanks for the suggestion.

Hello!
It is my first time reporting a crash of factorio.
I have this irritating crash that keeps occurring, I can sometimes make it from one autosave to the next. I have had similar crashes in various other games in the past also.
I can't make heads or tails of the log, please help me understand ...
