I'm running the recently updated Daz. This happens on most every character when I apply the GP and then adjust the height. It's like the GP is fixed in space.
It is happening on G8F and G8M base models as well as other characters. the 8.1 models do the same with GP 8.1 items.
I haven't tried removing it and reinstalling yet since I figured there was something in the software that was locked somehow. It worked previously until about a month ago, the NV8 still works just fine.
