Here you go:
By the way, the *only* way to code an item exchange is to create it in the receiver's inventory before deleting it from the giver's in order to avoid the item being lost altogether in these very instances. That is rigourous code. The problem, of course, is it creates the opportunity for duping. Individual item numbers would have fixed that, but this being the first game of its kind I guess no-one foresaw the prospect of server-wide duping. Individual item tagging is standard practice now. I'm reasonably certain item exchanges are coded in a slightly different way too (a type of database escrow).
I know the same issue could happen on death - I died on Live once and when the server came up I was at my spawn point fully clothed with a full inventory. I went back to my camp and there was a fully clothed corpse, including my epic (so I had to delete one - that was the most difficult delete I ever did). I didn't want the second version left around anywhere incase there were checks. I profited in a small way because non-lore items were lootable so I took them. I felt bad about doing even that, so whatever I couldn't use was given away or destroyed.

Same thing happened to me during live, I died during extreme lag, came back and had a full corpse. I went back out to the same camp I was at and saw my corpse on the ground. I wonder if a method of this is being used to dupe. Too bad I was only in my 30's and didn't have anything of value.
Do you remember the exact scenario in which this occurred for you? Maybe if we can create the same environment we can reproduce the issue on p99.
