It isn't the HID Tina. It's the Virtual_World Tina.
Yeah, although it includes the .png icon, it's missing the .dsf file for the bodyshape/blendshape (_bs_).
It still loads, but you only get the head and neck morphs, proportions, and such. I looked at the promos and they do seem to imply that a body morph is part of the package.
Of course, a different body morph could be applied. But it'd just a workaround and wouldn't solve the mystery.
The problem appeared while I was cleaning the G9 loading log entries. In the absence of the body morph the other loaded morphs of the character start throwing error messages on loading any G9 character.
As of now, I have deleted all the morph files of this character from the data directory to clean up the G9 loading log entries, so that the texture maps of the character can still be used.
The character was released a few months ago, but I couldn't find anyone complaining about it in the Daz forums, so I assume this issue may have been fixed by the vendor in a subsequent update.
