Bethesda says it has released a second update to Fallout: New Vegas which is available now via Steam. This second patch solves issues with autosave and quicksave features.

"We are also pleased to say that we have just released a second fix for PC users to address the autosave and quicksave issues that some people were encountering," explained senior producer Jason Bergman. "That particular issue was never seen prior to release and it was extremely difficult to reproduce reliably, even after the game had launched. In order to fix this problem we have had to disable Steam Cloud functionality. It has been turned off, and we won’t turn it back on until we’re absolutely sure it will not cause any more problems. Please restart your Steam client to make sure you get the update."

An update for the Xbox 360 version - which solves scripting and other bugs - went live overnight.
