Subject: [PATCH] Prevent Saving Bad entities to chunks
|
|
|
|
See https://github.com/PaperMC/Paper/issues/1223
|
|
|
|
Minecraft is saving invalid entities to the chunk files.
|
|
|
|
Avoid saving bad data, and also make improvements to handle
|
|
loading these chunks. Any invalid entity will be instant killed,
|
|
so lets avoid adding it to the world...
|
|
|
|
This lets us be safer about the dupe UUID resolver too, as now
|
|
we can ignore instant killed entities and avoid risk of duplicating
|
|
an invalid entity.
|
|
|
|
This should reduce log occurrences of dupe uuid messages.
