Please help! I am brand new...purchased CTA4 about ten days ago and of course one of the first things I am trying to learn is replacing a G3 character head with a morph based head. I get through the process fine until the head goes to the body. At first it was just popping in anywhere and though i could move it I could not attach it. I then started clicking on the neck bone to turn it blue before I started creating the head, then the head would pop in at the neck but rotate from the center. After about two days of trial and error and searching out Youtube videos and training videos, I double clicked on the head which brought up the sprite editor. I was able to move the head into position with a tiny green node (pivot point?) following it and somehow got the node on the neck with the head in position where it will now swing from the neck. So now I can do that much although I know I'm not doing it right. Mainly because I discovered that even though I can now get the head to pivot on the neck, the head bone and head nub will not attach to the head. I tried removing the head bone and then adding a new bone from the neck to the top of the head but the head bone and the head itself still swing free of each other. 
The answer is probably very obvious and I am frustrated that I can't figure it out myself But I would greatly appreciate any help anyone could give me.
