Using redirectPlayer creates a "dead clone"

[relvarten]

I mentioned this in the comments on another post, but I guess it deserves its own thread.

The problem is:

When you do redirect a player to any server (current, or another – does not matter) using this:

redirectPlayer(source, "", 0)

Then a clone appears in the game, occupying a slot and the player's nickname:

In the first seconds it says that the nickname is unavailable, but then I can log in under the same nickname:

When trying to contact a clone (by server or by another player) the server console will spam this:

Just for cleanliness:

1) I use this to completely reset players after restarts. It's not rational to do this in other ways (for example, client events cannot be reset correctly in any other way).

2) The redirect worked fine until recent updates (I think it was still fine about a week or two ago).
