The game is no longer giving me medals for multikills nor killstreaks. It has made the "defeat 3 enemies without dying" bounties and double kill bounties impossible to complete. I have been having this problem for a couple of weeks now. Even the last game I played I had a KAD of 6.33, but did not complete the "kill 3 without dying" bounty. I thought this bug was destiny wide, but my clan mates told me it sounds like an account specific bug. It's frustrating because I recorded what I believe should have been my first ever seventh column, but due to the bug I got nothing. Solved. Console needed to be fully turned off to clear the cache. I had just been using rest mode for a couple of weeks.
