I started Iron Banner quest on Titan and got to Step 3 (Earn Iron Banner Rank points). I swapped over to Warlock and picked up quest from Saladin and he was at Step 1 (Match Completed). After finishing a match, the quest progressed normally, until completion of Step 2 (Daily Challenge completed). Upon completion of step 2 on warlock a banner popped up that said Quest Completed and there is no longer an IB quest in my Warlocks inventory. I checked back on Titan and the quest is gone from there as well. There is no option to pick up a quest from Saladin on my Hunter. I can't recreate, and I am not able to get a picture or anything, due to the nature of this bug. Please fix. :(
