FAUNA Memory Fix (unofficial)

A one-file data pack that stops creatures built on FAUNA Engine, including every Book of Dragons dragon, from forgetting the players taming them and the dragons they live with.

The problem

FAUNA gives each creature an active memory of the individuals it knows. Once that list passes 32, the creature starts filing entries into long-term memory to make room. In a busy world the list fills up with mobs it has met (skeletons, zombies, creepers, wild dragons) that it can neither file nor forget, so it files the ones it can: the player taming it, or its packmates.

What you see:

  • The book's relations page drops to familiarity 0, fear 0 and liking 0 for someone the creature knew.
  • Taming stalls. Taming only reads active memory, so the dragon stops asking you for anything, or loses its progress.
  • Tamed dragons treat their packmates as strangers again.

The fix

The pack raises FAUNA's recent_rows memory setting from 32 to 128, so filing doesn't start until a creature knows far more individuals. Nothing else changes. Entries that were already filed come back the next time the creature sees that player or dragon.

It applies to every FAUNA creature, wild or tamed. It doesn't change how many dragons you can tame or own.

Install

  • One world: put the zip in saves/<your world>/datapacks/, then reopen the world, or run /reload with cheats on.
  • Every world: with Open Loader, put the zip in config/openloader/data/. With KubeJS, copy data/faunaengine/fauna/memory.json from the zip to kubejs/data/faunaengine/fauna/memory.json.
  • Server: put the zip in the server world's datapacks folder.

Versions

One zip works on Minecraft 1.20.1 and 1.21.1, on Forge and NeoForge, with FAUNA Engine 1.2. A later FAUNA update may fix or rename this setting, so check the changelog before relying on it.
