Seems like an "r-" was added before all the UIDs, whereas the UID view still exports without that "r-". All you have to do if you already have faces generated is go into config.xml in your graphics folder where the faces are, and under all the records, add in "r-" (without quotes) before the UIDs.
For example:
Change from:
<record from="Asian/Asian1916" to="graphics/pictures/person/2002116770/portrait"/>
To:
<record from="Asian/Asian1916" to="graphics/pictures/person/r-2002116770/portrait"/>
Fast way to do it would just be a find/replace all in notepad -- find "/person/" and replace with "/person/r-" (both without the quotation marks). You're probably gonna have to do this each time you generate from now on unless either it's fixed in FM or NewGan comes out with an update. You CAN go into the code for NewGan to change this as well but I wouldn't do it unless you know what you're doing lol.
Hope that helps!
