"The Harder They Fall" bounty (10 mini boss kills) does not work if the Vanguard Playlist Ops mission is a BattleGrounds missions. It only counts bosses if they are in Strikes. Please change it to so that any BattleGrounds mini boss kills count. Otherwise, my current behaviour of leaving any BattleGrounds missions that shows up in the Play List as soon as I spawn in. Also hire some Q&A people that report this crap, rather than relying on destiny Players to find and report these issues.
