So I am in the process of updating all of my skins with better descriptions and have been adding tags. Well on one of them I am getting a this skin already exits error and is not letting me update the skin. However when I go to click on the link that is provided, it takes me to a this skin does not exist page. I have restarted my browser and even used other browsers (chrome, firefox, ie) , but the problem still persists.

the skin in question is my black mage skin.
