.The most recent is doing the thieves guild quest for stealing the count's ring back, and when I checked my 104% camo to make sure its on, I noticed the numbers for it disappeared...
Then I casted 20% camo on myself, and checked to see if the numbers are fixed...
Tab > Magic > Last Tab to the right > Crash....
EDIT: Another crash... standing in front of Sk'riva's house using the wait button over and over again...
EDIT#2: I notice it will crash if I play it for more than an hour, usually repeating the same actions like training on Growlf's Training dummy with hand to hand, and knocking that deer everywhere. The only issue is that this isn't a oblivion crash lol, I think its a hardware issue, as I get this from surfing on the web browser too.
