Sunonymous: I have the same issue. Does anyone know where Fez stores the actual save files? It'd be useful to back it up. I've played through over halfway two times now before a bug rendered my saves unloadable. This last time I was at 77%. :/
I've considered copying the entire game folder and overwriting it if the issue happens again. I haven't tested that to see if it works though.
hansschmucker: It's at %APPDATA%\Fez and it also contains a backup of each savegame :)
Thank you! I always forget about the AppData folder. I'm so used to looking in the game's program files. Much appreciated!
However, I also figured out that if I use Fez's in game Copy Save Slot menu option and move a glitched save into another (I used an empty) slot, it loads again! I'm not sure if it would work for everyone, but it's worth a shot, right? I'm super excited again! I love this game!
