I've removed every plugin from my server, removed the world...I've done 3 fresh installs. So now i come to you for help. No matter what i've attempted my (PASSIVE) mobs despawn instead of going into a static position when the chunk is unloaded. I've tried spawning in mobs and waiting but they do not despawn until the chunk is unloaded when i fly away. I've also tested this is breeding and the issue remains. I fail to see what is in the configuration file that is causing this issue so any guidance or knowledge is much appreciated.
