I'll try to remember where it was... I'd just gone up the elevator, found I didn't have the access code, and so gone back down to the bottom floor. I was somewhere in the slums, but I don't remember more than that.
I think it's the fact that doors in and doors out look the same. So I go through a door inside a building, thinking I'm going deeper, and come out instead.
I think a fetch quest would help. It would feel less arbitrary if I were involved in fixing the elevator.
