This plugin causes entities from the scarecrows an murderers to infinitely grow.
Machetes, sickles, ect. Planners are the worst and I have no Idea why since planners are not dropped by any npcs.
This is caused by something improperly removing the loot when they despawn.

Is there anyway you could figure out the fix to this?

Do you have either "Kill Zombies" or "Leave Corpses" set to true?

Merged post

Setting these to false will prevent the corpses from being dropped and could help reduce the ent count.
