As the title explains, my saves on one PC aren't syncing up with my other PC. The game acts as though I've never played it before. I tried downloading the backup saves through the extras tab but still having trouble.

I feel that this game uses some kind of PC identifier on the saves, not just the name, messing the process. I've been trying the same thing with my deck. This page mentions it as a prefix for the file but changing it has proven useless to me.
