You need to delete all files in
%UserProfile%\AppData\LocalLow\Obsidian Entertainment\Pillars of Eternity\CurrentGame
%UserProfile%\AppData\Local\Temp
And most likely all stored files in
%USERPROFILE%\Saved Games\Pillars of Eternity (Except the save you want, but if the game has the same problem all over again, your save edit failed and the save is junk) So delete it, and quicksave out of an older save again.
If you still have saving problems, then I don't know
I'll try the third, I deleted the temp folders but did not delete all the other saves.
I'll try that, thanks!
Just be sure that you that you don't delete saves you actually wanted to keep, better to move them elsewhere just to be sure.
Yeah, I created backups of all of them.
I had already reinstalled the game, but didn't try it after doing that. I did remove everything from the save folder (and the temp folders) except the single, edited/cleaned quicksave that I wanted to keep.
Loading it worked fine, so I made a manual save and quit to menu and loaded it and it worked, entered into a house to create an autosave and did the same thing and it worked.
Seems fixed for me now, it's odd that just having other save games (all of which are from other actual playthroughs with different characters) screws it up that much.
Thanks for the help though.
