Temporarily disabled the Duty Officer recruitment assignments.
They will return with the Duty Officer expansion.
So unless I'm horribly mistaken the way this appears is that if we want new Doffs we either have to: (A) Pay for them directly as C-Store packs. (B) Purchase the expansion, again from the C-Store, just to retain in-game functionality that we had before today. Or (C) wait for the stars to align so Cryptic puts a new mission in game that contains a Doff pack as a reward (like this week's featured episode). And we all know how frequently Cryptic adds new mission content to the game.
