I've completed both my other two characters (Hunter and Warlock) with no issues, now, here I am with the blue armor set for my titan completed everything else but the solar super kills, arc grenade kills, and void melee. That is not because I haven't killed many enemies that way but it hasn't been tracking my kills or something and its been very infuriating because I'm so close but this won't finish now. Its been like this for a couple days.
