I set up a survival server on minecraft in 1.8 pre-release 3. When I updated it to 1.8, a bug occurred and keeps happening. This bug happens when my friends get a timeout error. When this happens a clone stays in-game.

After doing some test, we found out that the clones counts as the player, even if the player joins again. Killing the clone will kill the player when the server is restarted, all things you get when cloned is lost.

This has affected both my friends on Windows 7 and my friend on Windows 8.
