FoxyJGaming

I fixed the problem and then remembered this thread when searching for solutions. It apparently has something to do with achievements (even if you already have them). I don't know how it works but it does. What fixed it for me was opting out of steam beta. To do this go to Steam -> Setting -> Interface -> Client beta participation -> No beta chosen. Launch the game and your save should be fine. Hope this works for anyone having this problem I was frustrated for days.
