Subject: [PATCH] Duplicate UUID Resolve Option
|
|
|
|
Due to a bug in https://github.com/PaperMC/Paper/commit/2e29af3df05ec0a383f48be549d1c03200756d24
|
|
which was added all the way back in March of 2016, it was unknown (potentially not at the time)
|
|
that an entity might actually change the seed of the random object.
|
|
|
|
At some point, EntitySquid did start setting the seed. Due to this shared random, this caused
|
|
every entity to use a Random object with a predictable seed.
|
|
|
|
This has caused entities to potentially generate with the same UUID....
|
|
|
|
Over the years, servers have had entities disappear, but no sign of trouble
|
|
because CraftBukkit removed the log lines indicating that something was wrong.
|
|
|
|
We have fixed the root issue causing duplicate UUID's, however we now have chunk
|
|
files full of entities that have the same UUID as another entity!
|
|
|
|
When these chunks load, the 2nd entity will not be added to the world correctly.
|
|
|
|
If that chunk loads in a different order in the future, then it will reverse and the
|
|
missing one is now the one added to the world and not the other. This results in very
|
|
inconsistent entity behavior.
|
|
|
|
This change allows you to recover any duplicate entity by generating a new UUID for it.
|
|
This also lets you delete them instead if you don't want to risk having new entities added to
|
|
the world that you previously did not see.
|
|
|
|
But for those who are ok with leaving this inconsistent behavior, you may use WARN or NOTHING options.
|
|
|
|
It is recommended you regenerate the entities, as these were legit entities, and deserve your love.
