Are you kidding me? It costs a droid. So to speak "physically". At the same time, it is not "documented" (in the "companions" tab). Do you see such a magic window with the inscription 0/2 there? See that gray moiré on its icon? He did not check in either immediately after completing the quest to receive it, or later when leveling up with him.
Formally, I do not have this droid. But at the same time, he is. I don't understand what is the problem here? Why can't you just check the situation in the game and finally fix it properly.
