From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Optimise chunk tick iteration
When per-player mob spawning is enabled we do not need to randomly
shuffle the chunk list. Additionally, we can use the NearbyPlayers
class to quickly retrieve nearby players instead of possible
searching all players on the server.
