Hello. I have been having things disappear left and right from my inventory lately. I have boughten 5 tv's and each one has had to be replaces at least once...I have had cothes and jewelry also start missing. I am getting frustrated as one of the tv's was just bought yesterday and I just got a "Item won't rezz bcause it's not the database" type of message. Please help! I have losing 1000's of Lindens and about to give up. Thank you and Huggs. :-) P.S. When the items fails to rezz, it does NOT come back to me :-(
