The thing is, since I had problems with Hamachi, I suggested playing on GameRanger. Well, when we started, the opponent supposedly got an error after each turn, and the save wouldn't load, it would freeze. My turn always loaded. After at least an hour and a half, we finally decided to try playing through Hamachi (thankfully, it seems to be working, but no one is pinging there for some reason). There were no more problems with turn passing.
Here's the save file for the game, it's a bit messy because the last turn was made by the computer, as I didn't bother to set up a program to automatically save each day...
