Certain double doors can't be placed without bb.moveobjects when in build mode, on the short wall height. These doors include the "Modern Planked Door" from Growing Together, "Arched Door with Double Panes" from Basegame, "Semipermeadoor" from Get Together, and " 'When You See It' Glass Door" from Spa Day (oddly, this door is only single tile...)
I have tried the other wall heights, and the doors will be placed according to those wall heights.
When placed with bb.moveobjects on, my sims will not register it as a door they can walk through even if there is absolutely nothing in their way.
