Can anyone please help me and tell me what I am doing wrong? I cannot get the mission for Infected, the Cure, or Khitomer. The only STF I have available to me is Terradome. Thinking that I had to do Terradome first, I ran it and completed it. Still, the game will not unlock any of the others. I am level 50, so its not an issue of level. I even tried to run it just by joining the queue without picking up the mission. Although I am able to do that and run the mission, I dont get credit for it at the end because I never picked up the mission.

I have asked some in-game friends who run these missions regularly, and they have told me that they didnt have to do anything special. They just pick up the mission from D'vak. Unfortunately for me, he doesnt seem to want to give them to me. Is there something I am missing here? Something I need to do?

They arent standard missions anymore. You play them through the que, and your reward is a bag of loot at the end.
