I've accepted a bounty "of iron banner" in this bounty it asks me to win 3 iron banner matches with the iron banner class, emblem and shader items equipped. I have bought the shader (million million) and equipped the emblem (sigil of the iron lords). I have won multiple times with these items on and the bounty remains at 0 out of 3. Has this happened to anyone else? Am I wasting my time trying to accomplish this bounty?
