Large map size (for the two games represented here, multiple crashes per game). Not loading games within games. Not doing anything special, no mods, nothing weird.
The crash is absolutely inevitable. I CANNOT play a game without it bogging down in continual OOM saves.
After I've reached the point of no progress in the current game, I'll try a medium map size.
There should be seven or eight (don't remember exactly how many) crashes, from two games, in the file I linked.
Do you want the .dmp file too?
