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.
