		- A levelDesigner put a bad Teleporter which teleport to an invalid position
		- The player teleport, but its position is invalid => crash
		- the next time he logs, it crashes at start, AND HENCE CANNOT ASK A GM TO TELEPORT HIM AWAY

		Other scenarios can happens like Data change, Continent change => Player no more at valid position etc...
