So I cleared Devil's Lair with no deaths with that one Bounty active for completing a strike with no deaths and it did not get a completed status. I thought it could have been a glitch with the entire bounty system, so I found a public event and gold starred it (bounty was to get 3 gold star pubs) and the progress updated. Could just be the one Bounty, but I posted the pic as proof from the alpha stat tracker.
