Some missions that reward you with a new BoFF -still- do not always give you the officer. It was the SS Azura mission that broke in this way right off the bat this time. And yes, its not in the assignment list.
This just happened to me with the officer we're awarded during the tutorial (right before the ship part of the tutorial). I selected an officer to complete the mission before beaming to my ship, but I never received the officer. This problem was reported pretty often during the beta.
