Mob Limiter

The Mob Limiter automatically detects mobs within a particular radius, and removes them depending on the rules set below. This is in place to prevent lag and make it fair for everyone to play on an equal field. ▸Try the following to avoid having your mobs despawning: ➥ Nametagging your mobs ➥ Spacing out your mobs, so they are not in the same radius.
NOTE: The radius is X blocks for each mob. This means to properly space out your mob counts, it needs to be double the radius for the mob.
Example: If you want more than 40 villagers, you need the next group of villagers to be 100 blocks away from the other group, allowing for a 50 block radius around both groups individually.
