So I logged in today, and after being removed from my FC housing (temporarily) I decided to go back to the apartment I purchased and stable my chocobo there. When I got to the building in The Mist, I was unable to go to my room. Looking at the rooms that were there, I noticed that the room number I had was taken by someone else...and all of my possessions were up for retrieval at the market. I'm not sure why my apartment was auto-demolished, being how I have been subbing for the past few months.
