For the past couple of days some of my bounties have no gotten checked as completed after I did what it said. Multiple times I would kill fallen walkers on cosmodrome or strike mission and it would say I didn't kill any for the bounty where you must kill 3 to complete. Eventually an hour later when I logged off and back on then it would register my walker kills. And just now I finished the story mission "The Archive" and didn't get a complete for 'Target: Grayliks, Winter Baron'. Also another pic from that mission : http://i.imgur.com/4d73D0i.jpg
