Factorio Forums

It looks like Transport drones is doing the bad allocation but that is causing Factorio itself to crash. The worse case I'd expect for a mod caused problem is a crash to main menu.
The problem seems to be intermittent. It managed ~30 autosaves since map start before it had the problem and I think the last session on this map crashed with the same bug.

Thanks for the report; that's working correctly. You ran out of RAM and there's nothing the game can do in that case except show an error and abort what ever it was doing.
