Should fix #1280 Citizens hijacks entity map, and im guessing under the right conditions the result might actually be null during entity creation Pre the cache patch, the id is looked up on save, so it was fine. Now, if its null and the save ID is requested, we will try to look it up again and cache it if found.

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.
