[] Items Work Strangely in Resort Skybox?

I’ve found out that it is very tricky to select or edit items in the skybox of the resort (At least the roof of the tower). In my resort I have built an office on top of the tower, but when I recently tried to edit some of its canvases it wouldn’t let me select them. I have determined that I can select items up there if I drag a box over them, but that only works if they aren’t locked (which the canvases are). The toolgun doesn’t do anything. Elsewhere, “in bounds” as it were, items work normally. I have no idea what could be causing this.
