I logged out in my mine next to ladder with all my nice items. tried to log back in and got the you are in occupied space message. had a alt go take a look and nothing had changed. moved all the items near the area away, so in worst case i could grab my items back. hit return home and logged alt to pick items. the items were all inside the walls behind a coal pile unable to be collected in a position that has always been a wall and never able to stand in that spot.
edit: can not log in at any place now. every time i try even in my home i get the occupied message.
