Finally got around to playing this game. I'm really enjoying it so far, I'd say it's one of the few times that a big game like this really lived up to its hype. But I'm having a problem with the sidequest "cloak and daggers." I knocked out Double-T, and took down the other gang members, but the objectives screen still says I have to neutralize the gangmembers. I can't seem to get the green checkmark next to that objective. I've reloaded and done over several times, but nothing seems to work. Even killing all the gangmembers except Double-T doesn't do it. Are there other MCB gangmembers outside that apartment building I need to take down, or is there something I'm missing?
