No, it seems you need to play the updated map. The game crashes on the 7th day. The first time, I restarted and it worked. The second time, I restarted about 10 times, but it still crashed.

It didn't allow me to capture cities, and the AI didn't seem to notice me for those 2 weeks.
No, it's a corrupted save file.
