PaperMC/Spigot-Server-Patches/0363-Prevent-Mob-AI-Rules-from-Loading-Chunks.patch
Aikar 459987d69f
More improvements to activation range, improve turtles
improved the water code so that immunity wont trigger if the entity
has the water pathfinder system active, so this improves support
for all entities that know how to behave in water.

Merged 2 EAR patches together, and removed an MCUtil method that
doesnt have a purpose anymore
