I am trying to complete the quest 'Beyond the Beef' it's kind of important to me since I feel getting to know the ultra luxe ties into the main quest under the side bets quest.
The problom is the game freezes and the audio skips like a scratched record whenever I try to speak with Chauncy in the steamroom at 4pm. So far the steam room or 'near' the steam room is the only time it will freeze. I can leave the Ultra Luxe, kill the whole lot of powder gangers, come back and it will still freeze around that time and area.
Any suggestions? Maybe A reinstal?

I'm having the exact same problem. Every time I try to talk to Chauncy in the steamroom at 4pm the game freezes and I have to hard crash it. I've sent Bethesda TWO emails in the last three weeks and they have yet to respond. Does anyone have an idea or an inside line to Bethesda so they might at least respond?
