[OPEN] Roof clipping through walls

This is happening to me too. For some reason, roofs don't consider rooms with half-walls or fences as enclosed "rooms" for the purposes of not having the roof go through the walls.

For example: I wanted to make a two-story foyer that had stairs going up to the second story. I created the hallway upstairs by using a fence instead of a full wall - this created two rooms upstairs, I was able to delete the floor of the room over the foyer and place my stairs connecting to the fence wall. Everything works. Then I start roofing. In order to get the roof to look like I want, I had to drag part of it inside across the upstairs hallway and second-story foyer (open to below). In all of the rooms with full walls, the roof considers the room enclosed and disappears. In the hallway and open foyer, the roof doesn't consider the rooms as enclosed because of the wall that is a fence, and the roof shows up in the room.

Image 1 shows the room as one room, my workaround to keep the roof out. Image 1.5 shows where I had my fence originally, to create my two-story open foyer. Image 2 shows what happens if you put a fence there with my roofing in place, aka it deletes my stairs and the roof comes inside because the room is no longer considered enclosed.
