According to the UESP, my Xbox will tend to lock up if I try re-entering the Sanctuary after it's destroyed.

I just began the "No Stone Unturned" quest (For the first time in my entire year of playing), so I have 10 pounds worth of unremoveable gems now.

Is there a fix for this? Or is it absolutely permanent? It has crashed three times now (Twice from going there manually, once from actually loading the autosave it managed to give me).

That autosave gives me a glimmer of hope. Is it a case of constant reloading, in hopes that one sticks? Or will I be wasting my time?
