Hello, I'm playing Japan on the huge map but I can't get past 1808. Every time I end the turn it takes a very long time until eventually all the animations are stopped, the music stops, etc. The globe is still turning though. I can't do anything and can't even get it to close with Alt-F4. Ctrl+Alt+Delete and opening Task Manager works but if I Alt+Tab out the globe is still the cursor so I can't click anything, and then can't go back to the Civ window either. Trying to close it from the Alt-Tab window doesn't work either. The only way to exit is to Ctrl+Alt+Delete then Sign Out.
I've tried it many times, changing different things to see if it would be different. I changed to another civilization, I tried to autoplay to 1812, I saw there was a big war between Britain and India so I went to the Worldbuilder and deleted all British cities and units in India but nothing worked. I suspect it might have something to do with Mexico or Argentina starting in 1810. I deleted all cities and units in Mexico and Argentina and another time changed the cities there to Mexico and Argentina hoping if they existed already it might work. But no luck.
Here is the save game. I'm on the Git version but only up to the updates before the post you said would break saves. I have the soundtrack module but since it wouldn't work right I had replaced the CIV4GameInfoSchema.xml with the updated one and added the songs from DoCSoundtracks_CIV4EraInfos.xml to CIV4EraInfos.xml and copied it and put it in the Soundtrack module folder, renaming it DoCSoundtracks_CIV4EraInfos. I've had no problems with that besides having to redo that every time I update.
I attached the Python Error log as a txt file.
