Players are able to use alt accounts and enderpearls to travel long distances utilizing the pearls in unloaded chunks and loading the chunk later when convenient. This disables that by not saving the thrower when the chunk is unloaded. This is mainly useful for survival servers that do not allow freeform teleporting.
