My hatches are falling through my horizontal Pneumatic doors and the permissions aren't working.

I think permissions don't work for any type of horizontal door.

Yeah permissions don't work for horizontal doors, pretty annoying.

I can also confirm that hatches fall through them even if the door is not open.  I actually used that to my advantage to be able to bring the hatches where I wanted.

They also get trapped in vertical doors if the door doesn't have have a roof. They jump on top of it and fall in it.  Very useful to trap them so they stop moving for a while.

permissions work on horizontal mechanized airlocks, theyre just reversed. they dont work at all on horizontal pnuematic doors, even sometimes locking them doesnt block dupes. i like that stuff falls thru them though, that makes the actually useful for herding hatches and puft slime farms
