+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.
