Hong Kong time: 23 Dec around 16:00, I found that I am disconnected from my friend's room with an auto update (?) and returned to my room which should be the one I created yesterday base on the Miku DLC room, but it turned into an empty japanese style room.

I am trying to restore my room by digging the gogh bin files, but I dont have too much hope on this.

I will worry are my other rooms going to meet the same problem later on. Please give me and other players who lost their rooms an explanation.
