While it wasn't really "broken" before, if plugins use NMS (which they really should't be) and mess with entity management themselves, and get it wrong, they could ultimately corrupt our state expectations. I've been unable to reproduce any issues locally, but these changes are the result of me analyzing the code pretty deeply and seeing about how to make it more durable to abnormal usage. Any servers seeing oddities, please run with -Ddebug.entities=true and send me any logs triggered.

Subject: [PATCH] Fix Sending Chunks to Client
|
|
|
|
Vanilla has some screwy logic that doesn't send a chunk until
|
|
it has been post processed. This is an issue as post processing
|
|
doesn't occur until all neighbor chunks have been loaded.
|
|
|
|
This can reduce view distance while generating terrain, but also
|
|
cause bugs where chunks are never sent to the client.
|
|
|
|
This fix always sends chunks to the client, and simply updates
|
|
the client anytime post processing is triggered with the new chunk data.
