You can see and walk through it lol...
You'll have to show me where, I can't do either of those things since I swapped out the doors after paragon posted hopefully fixing it. I just went there and tried to get in with no doors open, and the character can't seem to find a hole to get through, despite it saying that he can.
Edit: Fixed, I figured it out. It was actually something I did while playing around, all it took to fix was a map regen. Not so much a bug, as me being an idiot
