I have had this happen to me two times now.
Without provocation, when I open up an existing daz (now .duf) file my shaped genesis character has exploded and looks like the attached image. The last time I used the file my character was perfectly fine but then after saving and then reopening he turns into a useless mess. There seems to be nothing I can do to fix the file and so I have to start from scratch and rebuild the character.
Has anyone else had this? As I said, this has happened twice in the last week with two completely separate files but both using the genesis character. Each time I have had to start afresh and have wasted many hours.
