With Siptah hair and especially beard colors changed. Now while you can still get maybe desired color with hair by modifying your existing character, there is no matching beards as they are unnaturally dark (you cannot have blonde beard for instance).
I have noticed the same, something seems very weird. Especially the parting of the hair looks weird to me now, it looks like it’s completely bald if I look at my character from the front but if I turn the camera up to see my character from the top, the hair in that spot starts to slowly reappear.
This is especially noticeable with blonde / light hair colors but even the darker hair colors have this issue if I look at it very closely.
I realized there is bug report forum, so I moved the topic there. Please if everyone has anything to add to the topic to help Funcom to fix/reproduce it, post here:
