I just picked up NTT to play with a friend and saw that it auto-unlocked all characters/crowns/stuff for online mode. Makes sense and was cool to play around with everything but then when I quit playing co-op I noticed everything was unlocked in my local game too now... I was really looking forward to unlocking everything myself. Is there a way to revert my game to the way it was before I played co-op mode online with just the achievements I've earned?
