I have the same problem on my lvl 58 sage. I queued for a random tactical fp and got legacy of the rakata. The day after I got to the stage of forged alliance that i needed to do legacy of rakata and now I couldnt queue for it with group finder or get the quest from the droid. I could do the solo mode of it though but once that was done I now cant do it any way. I also didnt get the daily reward from doing random tactical fp.
