When I exit my house (a treehouse, partway up a tree), I don't end up on the branch right outside--I fall through the branch and end up on my neighbour's roof. Same thing happened when I visited a friend's house. The game is somehow not recognising the branch right outside the door as a solid thing you can otherwise stand on. I can stand on it just fine when I approach it from outside; it's only when exiting that the fall happens.
Is this happening to anyone else?
