Subject: [PATCH] Fix issues with entity loss due to unloaded chunks
|
|
|
|
Vanilla has risk of losing entities by causing them to be
|
|
removed from all chunks if they try to move into an unloaded chunk.
|
|
|
|
This pretty much means high chance this entity will be lost in this
|
|
scenario.
|
|
|
|
There is another case that adding an entity to the world can fail if
|
|
the chunk isn't loaded.
|
|
|
|
Lots of the server is designed around addEntity never expecting to fail
|
|
for these reasons, nor is it really logical.
|
|
|
|
This change ensures the chunks are always loaded when entities are
|
|
added to the world, or a valid entity moves between chunks.
