Patch 1.4 xbox
Freeze upon trying to enter the Understone Keep.
Freeze upon trying to enter the Dead Men's Respite.
Freeze upon horse riding.
Freeze upon traveling through certain areas.
I got my value about 100 hours ago

I have the Understone Keep freeze...
And
Now freeze on entering Dragonsreach
Freeze walking on
roads - almost invariably - i have to try the wilderness to get anywhere - for some reason that appears safe for now!
Bthardamz gives me a puce green blank texture on entering a level, effectively killing any change of "The OnlyCure" being completed
(The same blank texture appeared in the Dark Brotherhood Sanctuary, but mysteriously corrected itself overnight!)
Numerous "broken" side quests - including "Disrupt the skooma trade" - so I'll never get the Riften house....
At this point , I am really getting ready to quit.
I loved Skyrim when it played without the crashes, but after 300+ hours, I was finally (yeah) ready to do the Civil War. Its the only main quest I have left. I am seriously bummed.
