Drawing not following pegs after adding curve deformers

So I have a head on a drawing layer that also has a peg layer. I added curve deformers to the head that are in a group between the head and peg layers. However now when I move the drawing layer, peg or even the neck peg, the head won’t follow. (though it does when I move the body peg) The other facial features move but not the head and I can’t work out why.
Wondering if anyone might have any ideas.
Much appreciated

You did not show the entire Node structure so I cannot see everything but adding a Master Peg over the Head and Neck Pegs will allow you to move those objects at the same time.
