Title: New teleport-up system for all arenas, in case of falling under the map

Since there are still some issues with the MovementGenerators, I suggest using a better way of handling players who fell under the map. My fix will be checking for each arena separately whether the player is under the map, rather than checking if their Z coord is lower than -500 (as currently implemented).
