Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable. It should be noted that this decision does not promise all future exploits will be configurable.

Subject: [PATCH] Fix client lag on advancement loading
|
|
|
|
When new advancements are added via the UnsafeValues#loadAdvancement
|
|
API, it triggers a full datapack reload when this is not necessary. The
|
|
advancement is already loaded directly into the advancement registry,
|
|
and the point of saving the advancement to the Bukkit datapack seems to
|
|
be for persistence. By removing the call to reload datapacks when an
|
|
advancement is loaded, the client no longer completely freezes up when
|
|
adding a new advancement.
|
|
To ensure the client still receives the updated advancement data, we
|
|
manually reload the advancement data for all players, which
|
|
normally takes place as a part of the datapack reloading.
