	   We create a connection count for each playerid and increase it everytime the according playerid
	   connects or disconnects. We also pass the current value of the connection count to the 
	   OnAccountLoaded callback. Then we check if the current connection count is the same as the one
	   we passed to the callback. If yes, the data belongs to the correct player. If no, it's the wrong
	   data and we just safely kick the wrong player.
