Subject: [PATCH] Don't move existing players to world spawn
|
|
|
|
This can cause a nasty server lag the spawn chunks are not kept loaded
|
|
or they aren't finished loading yet, or if the world spawn radius is
|
|
larger than the keep loaded range.
|
|
|
|
By skipping this, we avoid potential for a large spike on server start.
