In case this hasn't been reported, I was not able to launch a closed fireteam into any activity on the director. After a few seconds the UI returned to it's state prior to choosing to launch/search. Opening the fireteam up enabled match making to take place. This happened on two separate occasions after which I abandoned the use of closed fireteams for the beta.

There appears the be several issues with fireteams in the beta. We were having issue with one member being dropped on the way in, followed by a couple being dropped, but the game must have thought they were there because we had to play two v four the duration of the match.
