A similar problem. The mission didn't have the blue dot like in the video. I had to walk right up to that spot before the option to put in revealed itself.
Thanks for the help. The game decided not to light the spot up with the usual blue dot. I was wondering if I was even on the right spot until I saw your video.
If you go back to her she actually offers this quest. I had Bounty Hunter as my background so might have missed it first time. Not sure if this will work for others. I had left Cydonia and came back.
Why is it missable? Missable means it will disappear if you ignore it. I saw her but Ignored her and didn't talk to her. Does this mean if I return there I won't find her anymore??
