Genesis 8 body morphs
I have Daz Studio 4.12 pro. And I loaded the Genesis 8 character into the studio and it morphed. Not the entire body, just the hips and mouth. And the same morph happens when I load any Genesis 8 character. And that morph stops me from using any other morph. I tried to reinstall the character, and it still morphs. I tried to reinstall the studio, and it still morphs. The only way to stop it from doing that is to load the morphed Genesis 8 character, zero the body shape, find the characters body shape that I want to use and apply it. Is there anything that could be done about that?

You have probably installed something that overwrote the Genesis 8F base you need to find the character/morph and unistall it.
That is the result of badly packaged morphs/characters installed in your system, they have morphs saved with non-zero default value.
Re-installing Starter Essentials does not work, because the problem is not with the base figure but the morph/character that has been installed.
To fix any ill-behaving morphs, do as follows;
1. Load your base figure or the developer version.
2. Select "Show Hidden properties" in the Parameters-Tab, drop down menu (right-click)
3. Zero the figure (Found in Parameters-Tab, drop down menu)
4. Memorize the figure (Found in Parameters-Tab, drop down menu)
5. File->Save As->Support Asset->Save Modified Assets
This procedure will zero the default value in the ill-behaving morph/morphs, and while saving DS also shows you a list of the morphs it is changing.
