I dont know about the other classes , but with the female DH when i try to dye my character, at the front the new color is ok, but the back color is bugged and stays the previous color. Here is an example:

I have dyed my clothes in the Ranger's dye color and after a while I want to change the color to Winter dye. So far so good, but when i change it, it only changes the front of my character's armor and the back stays in the Ranger's dye color.

This is starting to get a bit annoying and I hope that you could fix this soon. Thank you in advance.
