Really? How could this not have been fixed before release? Was this play-tested at all? I've found some evidence that I'm not the only one - http://www.giantbomb.com/forums/the-elder-scrolls-v-skyrim/6593/evil-in-waiting-quest-glitched-or-just-me/526351/
Now, I'm either being really stupid, or this quest is really broken.
I mean, really? Could somebody not have picked this up? That and a College of Winterhold side quest, that is completely broken as an anomaly won't even open for me to close it!
Really rather poor... I understand that it's a big game, but I'm guessing they were being pushed real hard for 11/11/11.
