Spigot had code that returned early in chunk add/remove methods. This was causing our code added to set current chunks and counts to be skipped over if the entity was default not persistent but made persistent. This was the source of many issues Fixes #1208

Subject: [PATCH] Fix Bugs with Spigot Mob Spawn Logic
|
|
|
|
Spigot drastically altered vanilla mob spawn logic and caused a few issues.
|
|
1) Used only spawnable chunks vs entire world for entity counting, resulting in ignoring
|
|
other entities in the world, and causing the world to go over its intended limit.
|
|
|
|
Specially with servers using smaller mob spawn ranges than view distance, as well as affects spawning API
|
|
|
|
2) Spigot was using 16x16 division instead of vanilla 17x17 division.
|
|
|
|
This patch returns mob counting to use all loaded chunks, and 17x17 division.
