Many times I have attempted to drop items where I didn't have the right group title set and the item seems to just be 100% gone. Now I've lost a very costly item. Where do these things go and how do I get them back? ''''''''''''''''''''''''''''''' To the reply below. It must be something more. This is repeatable. It's not anywhere on the sim, even 0,0,0,0. It's not in lost and found or any part of inventory. The owner did not remove. This is instant. From inventory (no copy item) drag to ground (without prem to drop/rez items) to gone. Thanks,
