Delay the loosing players player data restoration by 20 ticks (one second), resolves the player data not being restored, seems the player needs a second or so to respawn (similar to when a player joins the server).
Remove the playerdata restoration messages unless there is an error.
Fix spamming of you have no duel requests from PLAYER error messages when you accept a duel. This doesn't show initially, but if you send another duel request this message will show X the times a duel request has been sent.
