Playing multiplayer: 2 players/Huge map/Terran/Altarians as players, other two races are Drengin and Iridium, AI control.

Game has been suffering the odd crash now again, usually every 40-60 turns, not consistently. Was always able to reload from an autosave without any problems. Now however, can't progress onto turn 204. Either I'll crash or my mate will crash, and I'll crash shortly after. This is consistent and happens every time.

I've tried reloading from an earlier save and it will crash on turn 204 regardless.
