I'm not sure if this is a bug or a feature of multiplayer minecraft, but I thought hostile mobs were supposed to despawn when the chunk they're in despawns - bosses not included. As it is now, they don't despawn. I couldn't find anything in the emc wiki about it being changed from vanilla. Does anyone know if this is intended?
From the MC wiki: https://minecraft.gamepedia.com/Spawn#Despawning "The chunk the mob is in must still be loaded to the mob to despawn. Otherwise the mob is frozen until the chunk is loaded again when the player approaches it, "
