A couple hours into a session last night I tried to quickload and I get "Savegame load failed. Error code(s) 304, 116"

I had been saving and loading with no issues during the same session. I just moved my party through the tunnel to the beach north of Cyseal. I did a quicksave and then after fighting poorly against the pirate/smuggles guys slightly north, I had to reload.

The error happens with all save files.

Any help would be appreciated. I'm hoping I won't lose my saves, but at this point I'd just like to play the game some more.

Thank you.
