EnderPearls | You can no longer hit GPS arrows with an ender pearl. This is actually a cumbersome task. To work around the limitations of the API, GPS will detect when a player is teleporting. If the teleport is caused by an ender pearl and it is right at a GPS arrow, GPS will cancel the teleport, remove the ender pearl, and spawn a new one with the player as owner and the same velocity. This does not affect the accuracy of the ender pearl.
