Mob Limits

Limits on Large Groups of Mobs.

To optimize server performance, large clusters of mobs are regulated.
Entities are not limited per chunk but are limited by their group (see below).
Groups of mobs that exceed the limit are periodically identified and culled,
exempting those with special characteristics like being a custom mob or tamed.
When a mob is removed, you will see a smoke effect.
