This only impacted people who used our useSnapshots new API in a plugin,
which obviously was no one as the data result was completely broken.
Merged the NPE check patch into mine since it has to handle it too.
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.
