I'm newly returned after 17 years or so. All was going well until last night when my Cu went wild and I lost it while trying to kill fire ants for a quest. Since then, I had my second Cu do the same thing but I recovered it. I have been feeding them and I noticed while fighting some Boura one of my Cu kept looking confused. Animal lore said it was Wonderfully happy and I fed it as well. Is there a bug or something changed I don't know about?
