It's a well known bug that if your bed is against an outside wall they can spawn inside your room. Try moving the bed to the centre of the room.
tried that, beds not against the wall either
created a new room with a new door (attached to main building) and it doesn't spawn.
moved bed back, does.
also if you fall into 1m of water it doesn't save you, but not sure if that's new with this or prev patch.
big bug is if you shift click to add something to a full chest it crashes the client.
