Can anybody tell me how to locate an object that is renewing itself every 30 seconds or so? I have managed to establish it is temporary by a modified script which looks for ghost prims on a sim. The problem here is that the object is owned by a parcel neighbour, who says he has no idea what it is. When I return it, it is obviously not going back into his lost and found as a normal object would. A short while after I have returned it, it's back in the list again. Because his sim has over 2000 objects anyway the object area search from phoenix is swamped, and cannot be filtered to only objects owned by him but in my parcel. I have tried turning on beacons and checking ashow updates, and stared all around, but still no sign. Any ideas?

We've just come up against this problem too. Someone rezzed an item that they had been offered by an unknown avatar, declined (twice), and yet it was still in their inventory. When rezzed, it could not be taken back or deleted, and even as landowner, i couldn't return it. They tried my advice of deleting all scripts inside the linkset and creating a new script that had an llDie() in the touch event, and couldn't even get that script to run. Finally, they got the advice here about wearing it to work. It went back into their inventory, but the 18 prims are still used up from our allocation, and an object area search can't find it in-world. Is this the old Ghost-prim issue with a new twist ? Should somebody raise a fault on this?
