Subject: [PATCH] Block Enderpearl Travel Exploit
|
|
|
|
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.
|
|
|
|
Note: Currently removed as enderpearls are ticked as long as their owner is online in 1.21.2.
|
|
Might be worth to re-add once an option to disable the above vanilla mechanic is added, to
|
|
fully prevent enderpearl travel exploits.
