I was told (as a miscellaneous quest) to kill a dragon on some mountain. When I got near it I saved, then approached the dragon for the fight. A few seconds into the fight my game froze and never recovered. I turned off my Xbox 360, waited a few minutes, and restarted. I chose the "continue" option from the game's main menu. It began loading, but then froze. Again, I turned off my Xbox 360, waited a few minutes, and restarted. This time, I loaded from the save just prior to the newest save (which was only about 10 minutes older). Same thing: the game froze during loading. Rinse, repeat, and I tried loading from a much older save with the same crashed outcome.
Background info:
My game is installed to the Xbox 360's hard drive
I have the newest patch (which I believe is 1.2, but it is the newest)
I have cleared the Xbox 360's hard drive cache (which required downloading the patch again) - this didn't help
Any help would be greatly appreciated. I'm 50 hours in, and there is NO WAY I'm starting from scratch!!!
