Hmm not quite sure what is going on here but i just tried to matchmake for the Russian Consulate hard mode daily, got kicked from the group after loading in and now i can't matchmake for it again because it's saying completed.....I got zero rewards either. /sigh
Restart mission on hard solo, once the mission is activated, open your privacy to allow any to join, your group will fill up with folks looking to match make and you will be leader.
