I play on gigantic map, already very late in the game with 9 civs. I have been at peace most of the game but now I started to kill them off one by one. I declare war on the drath, some of my allies are also allied to the drath and declare war on me. As soon as I press the 'turn' button the games crashes.
I've tried it 3 times now, every time I waited a bit longer before doing it but no success.
