While this method has async in it's name, it's not actually meant to be called asynchronously.... It just means IT will load the chunk asynchronously without blocking main. So fix this so that if a plugin calls it async, it forces the request back to main thread.

Subject: [PATCH] No-Tick view distance implementation
|
|
|
|
Implements world view distance getters/setters
|
|
|
|
Per-Player is absent due to difficulty of maintaining
|
|
the diff required to make it happen.
