Lol. 5x Commander rank BOff slots for me at the moment. The extra ensign universal, from my To'duj being set active, was gone when I logged on, which apparently unassigned all my BOffs... On slotting a Sci in the Universal Lt. of my Fleet Tor'kaht, it expanded to fit Tykens Rift 1 and Gravity Well 3. Everything else now accepts and uses commander abilities.

It isn't just a display glitch, I can fire off CRF3, APO3, RSP3, and EWP3, at least in the space around DS9.
