I logged out of a house and now I'm in the "basement" somewhere near Tisy outside of town. It's a lone, green, house that you have to take up a flight of stairs with one door. There is a living room with a half wall separating the kitchen. There is a secondary invisible wall keeping me from going under the kitchen where there is a mini door that you never were able to use.
I can't jump nor fully prone flat. I can crouch and move a little. I've tried walking backwards tapping X, running into a corner making the game shake like crazy, and trying to glitch through for hours. I know the easy answer is to start over on the beach but I put a LOT of time and explored the map 3 times over.
