I was bored today. I figured we need to list the possible solutions that are repeated. Maybe the site can add this to the top of the forum page.

1.) Complain about new patches that will never come

2.) Ask for petition for new patches to be shot down by admins

3.) Clear game cache : left bumper + right bumper + X

4.) Clear system cache: setttings - system setttings - storage or memory - clear game cache

5.) Remove and reload the game and add-ons from Xbox 360

6,) turn off auto saves because they corrupt the game

7.) Load previous saved game and start quest over

8.) Move on to other quests and skip over the ones that don't work.

9.) Turn off game and do something else that is less frustrating and go back later to the game

I have done all these more times than I can remember in 76 levels.

Did I miss any?

That would be a good idea. I think you pretty much covered all of the FAQs.
