For my account, any dyeable auras or flames or glows are glitched so that their color is locked to the color at the nape of my character's neck on medium or high shaders (ex: if my character's skin or longer hair is white, any auras are white no matter what color I dye them). This is consistent across my account and only affects my characters, it has been an issue for years, and I don't know anyone else who's had this issue.
Uninstalling and repairing the game have not fixed this. I do not have any shader alterations on this computer. Does anyone know what could be going on?
UPDATE: with the help of several people I've been able to narrow it down to some sort of computer issue. Not sure where it's stemming from since we've checked every corner of the hardware and graphics capabilities, but I guess it's just something to live with ir time to get a new laptop. I hope this detail might help anyone else who goes looking for this same issue!
