Subject: [PATCH] Improve AutoSave Mechanism
|
|
|
|
The problem here is that MinecraftServer.save(..), will attempt to sleep whilst all pending chunks are written to disk.
|
|
however due to various and complicated bugs, it will wait for an incorrect amount of chunks, which may cause it to sleep for an overly long amount of time.
|
|
|
|
Instead we will mimic the save-all command in its behaviour, which is both safe and performant.
|
|
|
|
Also, only save modified chunks, or chunks with entities after 4 auto save passes
