I found a cosmetic bug. After the 1.0.150192 Stable patch, good-looking beards have been added for all available characters.
I noticed that there is a problem with a fully grown beard. If you wear a mask with this beard, you get the old ugly beard back. I've tested if it's maybe not the mask, but if it just happens after some time. But after one hour with a fully grown beard later, I put on the Dusk Mask and after about 15 seconds I got the old ugly beard back.
