Ahhh, this well known bug :)

Go back to Daz and reset your M3 and both his body and head morph packages, then reinstall all 3. Things should work fine after that :)

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
