I can see the problem. And I already opened that cane of worms. I achieved the perfect bending with the second neck bone and... not a single face morph worked, the eyes, tongue and teeth are floating in space... really a funny experience. So I guess I have to re-shape all the morphs to the new head group geometry and get the head parts back to work in the dependence editor. Fine, I have a few days off left anyways, so let's go back to business.😳
