This usually goes wrong as early as during the character creation. If I create a new head, especially the five or so presets show eyebrows with a color similar to the hair and beard. But at some point, I *think* while I select a beard, the eyebrow disappears and there seems to be no way to get it back. What remains is a black eyebrow, regardless of what colour hair I chose, with no hair/beard-like shader texture on top of it. I think (but I'm not sure) that this black texture usually goes beneath the shader texture that does have the colour.
Can I get these eyebrows back somehow? In a running game, perhaps?
