Sometimes there's a morph that is pre-loaded onto G9 when you first load a G9 figure into the scene. So when you load a second morph over it, it looks like that. You should take a look when you first load a G9 character if there is a morph already loaded. It happened to me once, and couldn't figure out until I saw that there was a morph slider already at 100% right after loading a G9 into the scene. If you find this is the case, here's a fix from my friend
Jumbi :
In theory, these steps should get rid of the issue. I can't guarantee anything, though. Since it's not that big of a problem as it is now, I'd recommend you to wait for further replies from other members, in case there's a better/safer solution to the issue.
1. Load either the base G9 figure or the developer version.
2. Zero the figure (Menu Edit>Figure>Zero>Zero figure)
3. Memorize the figure (Menu Edit>Figure>Memorize>Memorize figure)
4. File->Save As->Support Asset->Save Modified Assets
This procedure will zero the default value in the ill-behaving morph
Hope it helps!
