If your Drygmy suddenly stopped generating items from a boss or an NPC, this pack is the likely reason. It stops Drygmys from farming certain powerful bosses and useful NPCs so you can't skip the challenge by collecting their drops passively.
Check whether the mob is blacklisted
1. Identify the mob in your farm.
2. Compare it against the blocked list. That list covers the Ender Dragon, Wither, Villagers, Wandering Traders, Evokers, Vindicators, Pillagers, both Goblin Traders, Ignis, the Ender Golem, The Harbinger, The Leviathan, the Archmage, Enchanter, Wilden Guardians, Stalkers and Hunters, the Dead King, Blood Servant, Evil Mage, Priest, Cryomancer, Apothecarist, Pyromancer, Ancient Knight and Archevoker.
3. If it's on the list, the Drygmy is ignoring it on purpose. This is not a bug in your build.
What to do next
- Bosses: Fight them the normal way to earn their special rewards. The pack is meant to keep big enemies challenging.
- Traders such as Villagers, Wandering Traders and Goblin Traders: Trade with them directly. Don't keep them trapped as farm fodder.
- Free up the space: Move the blocked mob out and replace it with an unblocked one so your Drygmy setup goes back to producing items.
- Mob isn't on the list? Then the pack isn't the cause. Recheck your farm against Ars Nouveau's normal Drygmy rules.
