I admit I am no game developer, but it seems to me that this would be an extremely simple thing to correct, I can think of several things they could do to simply remove this damn quest from my quest log, but I would be willing to bet a week's pay that they never fix it.
Some may think this is not a good enough reason to stop playing, but I do not share that view. This is an RPG...HELLO? the whole point is immersion and having things work correctly. I don't care how "huge" the game is, which is Bethesda's excuse for so many broken things, if the game is too "huge" for them to fix everything, then they'd better scale down their games and start making games that they can HANDLE.
And of course, they will not tell us whether or not they ever plan on fixing it...but common sense and their track record would tell you they never will.
And no, I can't go back and start at an earlier point to re-do it, that was eons ago and that save no longer even exists. You cannot keep an infinite number of saves, and who wants to have 5000 saves taking up all their hard drive space anyway? Skyrim is not the only game I play. And I was expecting that they would eventually fix it in one of the patches but I've lost that hope at this point, after how many patches?
You'll have to forgive me if I seem a little bitter, I am. I spent $60 on this game and have put 150 hours into it. I don't appreciate this.
