I put quite a few hours into the game at launch playing through to the end but missing the majority of side quests. Every time I have tried to play through again, I have been put off by what, for me, was a game breaking bug. Namely the one where your arms disjointed from their sockets and any held weapon moved to the top of the screen. I know I am going to be shot down in flames for saying this was a game breaking bug but it was for me as it destroyed any imersion, ie sneaking through a dark corridor then having to spin round on the spot trying to relocate my arms every few minutes,.
However this is not the case anymore. After a 16mb update, the biggest I have seen on the xbox, I can now sneak around with any weapon to my hearts content
Many thanks to whoever at Obsidian who fixed this, you have made me one happy bunny (just do it a bit faster next time please ).
