I have in the past encountered a morph or two, and when I tried to open via DSON Editor, I saw that the program threw me an error. That was quite a rare case for it. I threw caution to the wind and just ignored it at that time.
Now encountered it again with the Heidi character from 3DU. Is it just some data corruption or what? (Daz can still read the character fine and it's subsequent files)
Just wondering what's the issue is.
