Game keeps crashing

[unmerged(20873)]

Im playing a game as the Knights. I have installed IGC 2.3 and the enhanced AI for IGC. Im playaing the 1492 IGC scenario. Everything has run smooth untill around the years changes from 1512 to 1513. When that happens the game shuts down. The earliest crash was in early november, and the latest in late January.
Do anyone know a solution to my problem?

Sounds like a corrupted save to me. I'm afraid there's nothing more to do than start a new game.
