Well... the problem is certainly discouraging.
Like many other here, I was hit by the bug a couple weeks ago and have since leveled my guardian to 48. In the process of doing so, I managed to bring my Synthweaving, Archaeology, and Underworld Trading to 400 and Kira's affection rating to the max (10k).
Still, I have yet to receive a single mission from her. Many of us were under the impression that the bug would only affect her companion quests and nothing more, but I find that she continues to fail crew skill missions, or bring back meager resources, as if she still had a low affection rating.
I've compared her results to other companions with much less affection and these others continue to bring in better results (I've considered their individual bonuses which do not apply to this test). Despite her affection at max, I feel the bug forces her to operate at the affection level she was during the time of the bug.
IMO, Kira was not a make or break with regard to the JK class story, but I certainly feel that there is a gap in it because of the inability to progress her story. It feels like she's just dropped out of the experience altogether. We need this issue resolved like Guardians need more dps.
