Factorio Forums

Hello. My current save was working fine until yesterday, when the game started crashing and the box message said to me put the log here:
So... what could it be? I do not know how to save to a file...

This is a mod issue, some entity dying causes an explosion that causes entities to die that cause an explosion... until the stack is full.

This line tells me exactly what the error is:

ERROR: Factorio crashed due to Stack overflow.

This just means that something in the factorio code or the code of one of the mods you have installed was doing something too recursive for the game to handle. (the "Stack" here refers to a list of where the program currently is and has been - and a "Stack overflow" means that the stack tried to get bigger than the space allocated for it)

The fix is to remove the mod(s) that caused the issue. Sadly, due to the nature of the issue, I can't tell exactly which one of the mods you have installed caused the issue, but it definitely is more complex than the average mod.

I'd start by removing "Explosive Biters".
