I had played the old version before. I'm not sure:
I think I found a bug: When I enter an area through door "1" then leave the area through door "2" and then reenter the area via this door "2", I spawn in front of door "1" instead - just like the first time I entered the area. Did that make any sense?
Exit-Door 2
________________x (spawn point)
_______________Exit-Door 1
^^I think this is the arrangement of the two exit doors in the first study area. When I play through the map and exit through door 2 finally and then reenter via this door 2 - I spawn in front of door 1 as if it was the first time I entered the study.
