I've been reading about this bug for a while. Never had the problem, until recently. Recently re-subbed and the first time I went to my bridge I had clones. All of the bridge crew were my boffs... some cloned. Not one 'red shirt' crewman. (Those out of uniform npc's that infest your ship by the dozens even if you are flying an Escort... I have 50 crew, why are they all in the same hallway? )
This bug also appears in First Contact missions. A Science Boff usually is cloned in the reception room. Regardless, the bug is kinda obnoxious, but since it's an interior problem, it will likely be on low priority unless they just stumble into the fix.
From what I've seen (and this is purely my own opinion on my observation), we should not expect many bugfixes untill the game goes free2play.
What is priority right now seems to be things that can go into the C-Store... NOW NOW... don't get me wrong... this is a good thing... I expect prices on the C-Store to go through the Roof whent he game goes
F2P, so whatever we can get for "low" price now before they go up is a good thing.
One could also be optimistic, and expect that there will be fixes in 4.1-
