I don't really need an answer for this because I don't have this character any more.

But, it was my first character, I put over a hundred hours into it. I stored all my stuff in the Outcast Bunker from Operation Anchorage for a long time.

Until one day it froze when I activated the elevator. I restarted the Xbox, went to the elevator and it froze again. Tried entering different locations and those didn't freeze. Tried again the next day and activating the elevator still froze me. I even tried a whole new character and the elevator still froze.

Does anyone know what could have happened? This also happened to me on Skyrim with Breezehome.
