This game crashes whenever I end the turn. There must be some sort of bug. Everything is done, you just need to push enter, and it crashes to desktop with an error message. I tried loading earlier autosaves, but the same thing keeps happening, not always on this turn, but within 3-4 turns.

I'm hoping whatever bug that's causing this can get fixed, because I'd really like to finish this game.

It crashes for me as well and gives this python error for the Random Events code:
