Please see attached screenshot/photo of the bounty. My understanding is that multikills are 2 or more kills within 1-2 seconds of each other. Whether via repeated Ace of Spades headshots far within this time limit, a grenade or cluster bomb rocket into a group of 5+ enemies, progress is not recorded. The only thing I am able to make progress with on my 750 Hunter is my super. I'm not sure if this falls under the "[b]Connection Issues[/b]" category of known issues in [url=https://www.bungie.net/en/Forums/Post/252913995?sort=0&page=0]this thread from Bungie (last edited July 24th)[/url], but thought you may want to know. Cheers!
