PSA: This game has an amazing automatic save backup feature.

In your game's directory (Right click in Steam library go to properties, click installed, then click browse) go to > b1 > saved > saved game and there's loads of automatic backups. Very useful, I missed something in the game which would have locked me out of an achievement until NG+ but I found the backups and just reverted. Thought I'd let people know in case it helps someone.
