Factorio Forums

The game crashes randomly with a message saying, "Unexpected error occurred. If you're running the latest version of the game you can help us solve the problem by posting the contents of the log file on the Factorio forums."

Update: Added the save file

This suggests a hardware problem, make sure you are on the latest bios for the raptor lake defect. If you find a way to reliably produce the crash let us know, see 114778.

[2.0.72] i am also having this same issue and never used to have any issues at all. I am just playing the game and then this error message pops up and I do not know why. Here is the log file - and here is my save file - I am unsure as to how to re-create this as it just happens as i am playing and i am not really too sure how to read the log file as to what is exactly going on there to give any more info. All i know is it is making the game very unplayable and I am not getting anywhere anymore as it keeps crashing with this same error, I am unsure how to fix this, please help! I have 2,988 hrs on record and love this game and want to keep playing it!!! Thanks!
