Addition -- kit out main floor bedroom

I drew in a bathroom & a closet in the north room on the main floor:

Yes, the bathroom has a sliding door to the "inside" deck, why do you ask? :-)

However, what looks like an opening from the closet to the deck is just the software being weird. Also, the opening from the room into the closet should be centered on that wall, another bug. I think I may leave it as an opening though & put up a curtain rather than a door.
