When I try to select different colors for clothes the shop is not showing a preview of the color to be applied. This appears to only be happening to items that are stitched. I am also certain the item can be color changed since I can get an unstitched version and it will work as intended.
I have had the same trouble with the dye preview window since update. color changes do not show at all. however,if i take the chance and buy the dye change, it does work. it just costs a lot of gold if my choice was bad to dye again and possibly again. it would be nice if that could be fixed soon.
This has happened to me a lot recently, on not only one account. It started when the new update launched. This really bugs me because not being able to see if certain colors look ok together can lead to wasted gold when trying to figure it out.
