For the past week I have been trying to complete "Darkness Returns" and cannot do so. I have heard ot the glitch where Karliah Vanishes, though this is not the problem. She stays and the game tells me to speak with her after Nocturnal says her peace. This is where the problem comes in: When I speak with her all she says is "Yes, Fellow Nightingale?" and does not continue the quest. I have reload saves from before I even started the Theives Guild Quests and it still does it. I have left the area done other quests, return, and it still happens. Has this happened to anyone else? Any Ideas on what could fix this (Besides removing Cache on the 360 and loading past saves I have done this more than I can count). I hope the is a Patch for this quest and other quest glitches I have heard about to.
