I don't even remember telling Leliana to do this mission. It was just there on the war table at one point with the "active" card underneath it. I clicked to look at it and it said Leliana was on it, but it just sits there doing nothing. I've tried talking to both of them to no avail. But as I said, I really do not even think I ordered Leliana to do the mission, but I could be mistaken with the high number of missions available. Also, Leliana is available to do other missions for me as well.
