My issue was fixed in the 4.0a patch, what quest are you guys on specifically? The "reset" button will be greyed out if you are in an area that is involved in the quest: I highly recommend using your fleet pass to teleport back to the fleet, your reset button should certainly be enabled by then. If you reset it I'm willing to bet she will come back. Good luck!

Same here, Kira is missing for me, not in companion list or on ship. Shows up in cutscenes though. Hopefully this gets fixed quick.

Anyone else seeing this too? I hear companions are missing for a lot of people.

I'm in a similar situation although I'm not blocked by it: Kira is missing from my companion list after the update, she's not on my ship and I can't reset my quest chain to go get her again either. Stuck waiting for resolution on a ticket that will probably take weeks to answer.

Already did. No difference. I'm past the point where she becomes a companion anyway.

Kira dissapeared from my companion list after the update, I just got my ship and she shows up in the cutscenes but isn't in my companion list (only T7/C2 are there). I've reset my class quest but it made no difference. I'm on Taris right now.

Kira is missing for me too, I've since left Coruscant and she still isn't in my companion list. She does show up in cutscenes on my ship but other than that she is MIA.
