Do DS have to do anything special to complete the TT quests? My friends finished oblivion3 and none of them can get the oblivion 4 quest. I've seen KMS videos where DS have gone PB so I'm not sure if it's a glitch or if DS have to do something special. Right now they're completing the entire DS storyline in hopes in activates the obliv4 quest.
Some non-DS did their TT quests with them and they got the quest so I know it's not a problem in general.
New info: One of them just finished the entire storyline quest and they still can't get obliv4 quest to pop up.
