Supposedly that problem will take a programmer to fix, and since it's 'low priority' as it isn't bugging a mission up or anything, it'll be a while.
I'd rather they fix some missions that have been broken since they came out. I want my Mk XI TOS Phaser rifle, but Night of the Comet keeps spawning unkillable officers in the Drozana bar.
I had that happen once. When it happened to me they became unkillable if the devidians were killed first which is why I go for the mobs of my faction first before absence of the other threats take them out of combat and makes them unkillable like any ally.
