Played this game for last week or so. I usually dont reboot my pc for months. So i didnt this time either. But when i attempted to continue game from yesterday , game refused to read my saved game files. By checking location files were alight. So found this solution on very old obsidian topic about the issue.
Go to C:/Users/YOURUSERNAME/AppData/Local/Temp/Obsidian Entertainment and delete entire folder!
Theres nothing but junk in there. Boot game and game should see ur save files again
