[MC-64131] Clone of player is created if ReadTimeOut

When I get a Read time out, a copy of me is created, and you can kill it and get the items. So it is an item duplication bug too.

Environment

Not important.

If you leave the server and re login, you will die and your items will dissapear FOREVER

that's because you didn't kill hte clone, you contraolled a clone, so you killed yourselve, and lost all your items to the clone who disappears then
