I logged out of a green single floor house that has the stair case leading to it. I logged in and I was under the house and stuck. There was a small rectangular box that I couldn't pass through, I couldn't shoot though the wall, and I couldn't prone. The house around me was invisible except the objects on the floor above me. Eventually, I started running and crouched before hitting the wall, lunging me through the wall and allowing me to escape.
I recorded it and here is a link to the video:
