I figured it out. I moved one of the male face shapes to female to see if I liked it (I don't really, but maybe someone else will), and didn't include it in the packet like an idiot. The break in number sequence messes with the next face, and causes it not to appear.
If the new RPG Maker's character generator produces full busts and can match the art styles of previous RPG Makers, that might be a big incentive to buy it. An easier way to craft custom map tile sheets though would probably be an even bigger game changer.
