Just attempted a complete uninstall, shut down, reboot, install, shut down, reboot, play and the issue is still present. I verified the save file is in the correct folder after closing the game, but when I relaunch the game the "Continue" and "Load" buttons aren't selectable. Creating a new character and going to menu and trying to load from there only displays the autosave for that character. All save files remain in the "C:\Users\USER\Saved Games\Pillars of Eternity" folder after closing the game.
