Bred trader llamas still use the TraderLlama despawn timer. TraderLlama sets int despawnDelay = 47999;. Breeding (makeNewLlama with BREEDING) doesn’t disable despawning. Every tick aiStep() calls this.maybeDespawn(), and because the baby is not tamed by default canDespawn() stays true and with the timer counting down eventuallydiscard() is called. The canDespawn() check returns false if the llama is tamed, leashed to something other than the wandering trader, or has a player passenger.
