I had the same thing with freeze tag, and notified regas in game.
ALSO, this is the second time now... I log in, go to my house or guild house and start moving furnitures around... and when i come back it is just all GONE. no loading, no anything appearing for anyone else.. it's all just GONE. After the mini heart attack I left and came back to the program, and it is all there again.... really weird.
The previous time I had some one tell me to invite them to the house, and that seemed to fix it?
