"Beastmaster of Ilum", the Kath Hound entry is bugged
"Kill it with fire", kill 100 makrins with fire on Makeb is bugged
"Republic Containment Officer" I actually have the set, but It seems bugged to me,it doesnt count.
"Imperial Containment Officer" a set from the original Rakghoul Plague event that I dont have it.
Oh, thats unfortunate - wishing you luck that the devs are fixing them soon.
