On Farmhouse if you go upstairs then weld a double door, upstairs all the way outside on the stairwell to the left --when the door breaks you still see the weld but the door is invisible and you can't go past it.
Well, eventually after several rounds of the door being invisible with a weld right in the air just hovering ---eventually for some odd reason you can then pass through the door.
