Ok, I played this out right before I went to work. I moved Ptolemaios a bit north and hit 'end turn' (a bad CharacterTurnEnd trigger would take effect almost immediately). I didn't have a CTD. The AI turns started, I got attacked, autoresolved, and had a CTD afterwards during the AI turn. I didn't have a chance to fully examine the output of Filemon, but I'm pretty sure it doesn't have anything to do with the Olympics. I'll take another look at the dump tomorrow. From what I recall, it was full of more "file not found" error messages.

I will investigate the chances for Olympic victory, though. They may be too low.
