During the alpha one of my saves got corrupted and it has made the first save slot unusable. I have found no way to "clean" the corrupted save slot.
I've tried:
1) Deleting the save directly in the file system (under steamapps/blahlblahblah)
2) Deleting the save folder entirely
3) Deleting the whole game folder entirely and verifying game cache!
What is keeping this save data around, and where is it?
