I just completed the weekly Collect and Conquer bounty from the drifter in the Reckoning Tier 3. When I claimed the bounty if said Notorious Collector Mask but when I looked in my inventory it was only the Outlawed Collector Mask. I need Bungie to fix this. You can see that I did the Tier 3 because I also received the Notorious Collector Strides. I did notice that upon claiming the bounty I received a message about "maintenance beginning momentarily". I have been playing Destiny from the beginning. I am curious to see if Bungie is actually listening and helping it's loyal community members or if my putting this post here (which seems to be the only way of contacting anyone at Bungie) is simply an exercise in futility. I hate the Reckoning but have been slogging through trying to get this gear. Whether or not Bungie fixes this issue will determine whether or not I continue with the game. I cancelled my preorder of Shdowkeep and will wait and see if the company cares about its community or not before giving any more of my money to this company.
A kind soul pointed me toward a Reddit post detailing how to get around this. I have successfully done it and achieved my MMXIX title. As long as you still have any weekly bounty to receive a powerful headpiece from Drifter, you should be able to get it. For example, if you have tier 1 sentry headpiece already, then you simply need to go into tier 2 reckoning and wager middling sentry motes and you WILL get a tier 2 sentry headpiece to drop eventually. I got it as soon as I got the other pieces in the set. Then you can complete the powerful bounty like normal for the tier 3 helmet. If you don't have tier 1 headpiece for any other roles, then you simply load up reckoning tier 1 and wager weak motes until you get the headpiece, then continue on to the next step. Bungie should really have made these steps clear and it seems like a lot of people on the forums downvote these suggestions. Good luck! P.S. It should be noted this only works because you already have the powerful synthesizer and you have already unlocked a tier 2 headpiece for one role.
