The situation was as follows: I had problems with Hamachi, so I suggested playing on GameRanger. When we started, the opponent supposedly encountered an error after each turn, and the save file wouldn't load, it would freeze. My turn was always loaded. After at least an hour and a half, we decided to try finishing the game via Hamachi (thankfully, it seemed to work, although no one is pinging there for some reason). After that, there were no more problems with turn transfers.
Here is the save file for the game; it's a bit messy because the last turn was played by the computer, as I didn't bother to set up a program to automatically save the game each day...

I had a funny situation: the opponent crashed, I waited for him because it was a Tournament, and he explained that he had personal (home) problems (apparently, he couldn't write before that)
