I seem to be have an odd issue with a character i’ve created for one of my game projects. Everything seemed to be fine until i attempted to create a normal map

In the case of normal mapping their seems to be an oddity anytime i bake the normal map in that a section in the head and somewhere along the torso is missing. I entered texture mode and found that their is a part that does not turn pink with the rest of the model i believed it to be an overlay from another object however it is not.

This is my blend file the high poly figure is on the first layer and the low poly figure is on the second.
