I have written a complaint about this, March of last year, and nothing has been done. This bug is in the big area of the underground portion of the house to the left, as you are facing the door to the hallway. I would like this to get fixed please because I have plans to decorate the ceiling with dwemer pipes, and this is in the way.
If it helps, here is a link to the other screenshot I took:
