Thanks for the report, GRB! Can you tell which way you went that led to this issue?
Yes, I was in the steamy room in manufacturing, the one that has lots of doors that open with a specific key. I grabbed the chic key that was in there, opened the chic door, and then returned to the room you reach exiting through the left. That's when I got stuck. Hope I was clear enough explaining it, English is not my first language, sorry!
