Can we have houses that act more like the houses on 'the sims' where the walls on two sides become see through and the roof disappears(and the outdoors remains loaded)? That would help a little with black screens always popping up. The current system seems to teleport you to another dimension where only your rooms exist.
I have had some issues entering and exiting a house as well. That lag can easily get you killed(especially when a badger wandered up on your house while you were inside and upon exit have no means to run back inside).
