Now this is a strange bird. Do you remember what passcode you tried typing in (far stretch)? I keep trying to crash the password prompt too to see if I can replicate this, and I'm not having a ton of luck. The only thing I could think of is if the base version is trying to load one of the stages that doesn't exist, which would make the most sense. The build I still have on my computer is the one post-release that was going to add some new content, but that didn't go so hot. I'll have to take a crack at this one once I'm off work.
We do apologize for the chaos! Appreciate the heads up!
