Cursed bite on npcs - do they progress and gain abilities to become autonomous aggressive werewolves

I turned a bunch of neighbors into werewolves in my castaway challenge, to give my sims the challenge of sharing their island with "monsters" recently. But outside a full moon night the newly turned werewolves hardly ever transformed. It does happen, but it's rare. Since a newly turned were has only a single temperament, it takes long to build fury. Giving your npc Transformation Mastery might help.
