This is about Galactic Civilizations III on Steam. I doubled the number of factions when I recently started a new game. The new factions [all Mass Effect] were taken from the mod list available on Steam. Added some new ships too.

The saved game file had been taking a long to load, but just now for the first time, it Crashed to Desktop. Tried it several more times and with different save files, same CTD.

So is there a game limit for factions? Is the problem something else entirely? I've got an i7 with 12g, x64 OS. My map is Huge, with 20 players, game file 83k, Turn 200. 

I have Steam Client Booster and Nvidia GeoForce Experience active, if that has any significance.

Any help or advice is greatly appreciated.
