I am sure others have had this bug as well. But after the mission "Tradecraft" the next set of missions have not been activated. This could be level related I suppose. I will do some other non story missions and see if they unlock when I level up. I am currently level 15.
Oh!! Derp!! of course it is the level I forgot that missions have level requirements. It should be noted however that I have only been playing the story missions. yup and for the next mission I need to be level 16!
