Very odd. You can make bone cabochans at least, but mugs...hmm. I should add skull goblets to Adventurecraft. :V
Speaking of which, added the underground animalpeople back to the list of playable races. And did some tweaks to them, namely their sizes. Even at human size, a serpent man is not very high up on the food chain when you start on a monster island. Especially when the first area you encounter is a lair with about a dozen ettins.
