[GS] [1.0.0.341(443561)] Game crashes at turn 254 [reproducible]

[Pilsener Grease]

Playing on YnAMP Large Europe map (Dieter Von Clam's Large Europe, 79x73) with Eleanor of France, against 7 other AI competitors. Game keeps crashing at the top of turn 254, 1720 AD -- I've attached the save file for the prior turn. Turn 253 loads just fine, but the game crashes just before you can start 254. I've tried playing 253 a few different ways, but it keeps crashing. Help!
