I was enjoying Iron Banner 2.0 and hit rank 2 last Friday or Saturday. I already had the Million Million shader equipped, but when I went to Lord Saladin, he didn't say I had already purchased it. He did say I'd already purchased the first emblem, so I thought maybe the UI was bugged on the shader, or maybe this was a different variant of the Million Million shader. I was unsure what to do, that is until I accidentally hit the Acquire button. BOOM! 7xxx glimmer gone in a second and with it my hope for buying the boots Saladin had when I hit rank 3. I'm not sure why I'm able to buy the shader multiple times by accident, but not other items. Even if there's a good reason why you should be able to buy the shader, how about a warning when I already own one?
