I'm currently deeply involved in a game 100+hr's, Eternity speed Gigantic Map size, Flexible difficulty. My game will crash in 1764 AD, I've enabled the log, and looked at the in between turns (the AI research time changing). It seems to crash once it gets through 1/2 the AI's on the score board. System :- Ubuntu 12.04, 64 Bits Dual core 6 Meg of ram 1 Gig Video card. Any suggestions without having to look would also be appreciated. File exceeds the upload limits of 2 Meg, its 3.7Meg I can tell you its not the following: Video card size, drivers or operating system. Memory never exceeds 1.7 Gig in total for the system. Not game engine, I've had random crashes before, but always been able to play on. Nothing I"m building, as crash happens during AI movements.
