So I booted up my mod because I wanted to show you all a misunderstanding I created (the HP bar), and this happened. It's strange because normally the game's warped me out of the Hub into EggRoom 0. So I test the area and then fall into a pit. It gives the usual "You were never seen again" message before giving me the Yes/No promt. I say Yes, thinking that it'll take me back to the Outer Wall. Instead I get taken to Egg Room 0. Joy.
I'm going to assume this was a result of some scripting error.
