Funny, same thing just happened here too. Promoted my Lt. tactical klingon to Commander. Opened promotion menu, pressed the button - nothing happens.
Opened it again, pressend the button, nothing happens. Same again, nothing happens. Suddenly rank goes Lt. Commander, Commander, Captain.
Actually if you think about it there should be a BO captain, when your an admiral, strictly speaking from canon star trek admirals always take over command of someone else's shiip, usually when a multi ship task force is assembled for a specific task then disbanded afterwards.
Wasnt that the whole problem with kirk in the first place? being an admiral ment being deskbound and losing his command. Most admirals in star trek are shown either being pencil pushers or ex-captains who cant wait to use any excuse to temporarily take command of a ship.
Sooo when we're promoted to admiral we should have a BO as captain...
(TBH though top rank should have been captain that would have made more sense than a star fleet made up of 99% admirals which is what will happen within 6 months)
They should have made commodore and admiral clan/fleet ranks....
