@RexXxuS i had this happen a couple times when standing under one of the shutter doors as it closed on me. it pushes the player through the floor. usually end up on the ground and able to walk through the walls to get back outside.
on that note, could we remove most of the shutter doors now that they do not require a switch? some will obviously need to stay. i only suggest this because the open/close sound is one of the most annoying ones in game. the turret death closets can have the 1x1 shutters opening horizontally to avoid pushing players through the floor as well.
I honestly do not know, I was running back with the key I forgot to grab earlier and got close to a shutter door and was in this hallway. It happened extremely fast, I didn’t even see whatever this was happening.
