Awesome! That's good to hear.
As far as the one creature bug: I had my wolf, which I had boosted significantly with food. I left other slots open for taming, and had several critters in reserve. I saved, quit the game, and later returned. When I realized I had no more new tameables I could access, I tried to round out my party. When I did that, the game gave me the message saying I didn't have enough creature points. I could swap out other critters for my wolf, but if I tried to add more than one critter, regardless of what it was, I just got the message saying I didn't have enough points.
