This hatch spawn blocks a doorway on RPD
I wish I could have gotten a better view of the room, but the last survivor was literally dying and I only got this screenshot with half a second or so to spare.
With the hatch where it is, I (the Killer, Pyramid Head specifically, if that matters) can not walk through the open doorway shown in the screenshot. It it is because the hatch itself has collision that elevates me slightly and the top of my hitbox won't pass under the doorway. The map is Raccoon City Police Department.
I know this description will be bad but here it goes. it is the bottom floor, obviously. It is the room that features a mildly safe pallet loop made up of a bunch of those chairs you can see in the screenshot on one end. I don't remember what the other end is but hopefully that it is enough to go off of to replicate this and remove this specific hatch spawn. I also wouldn't be surprised if more spawns like this exist on RPD.
