Hair Auto-Fit problems with 4.15

Andreaswb

Hi,

I have some Genesis characters created with 4.9 / 4.10.
Now opening these older creations in 4.15 causes serious problems with some hair. The example I used is Duke-Hair for Genesis. Auto-Fit get not applied / activated. You can do it manually afterwards.

The moment you apply "Youth" morphs (i.e. Child-morph or Growing Up for Genesis) the hair changes the size and position as demonstrated in the attachment.
What is the problem over here? - Solutions?
