Could this be an "always open" door and not a click? I don't like it

This is almost certainly the reason. Every bit of the fort is carefully designed so no matter what state it’s in it’s logical if you see other players running through it in a different state. A lot of the blockage is because stuff is walls, buildings, or other scenery pieces in other states. Dinarrows uses a similar thing, rocks exist in place.
