Kotaku is reaching out to the game's developer to see if there are plans to patch Fallout: New Vegas and will update if we hear back.
Update: Patches are coming. Pete Hines, marketing man at Fallout studio Bethesda Softworks, tells Kotaku that "We are currently working on releasing patches/updates as quickly as possible for Fallout: New Vegas, for all platforms. Announcements regarding the patches are forthcoming." He advises anyone seeing this head-turning bug to re-verify their files on Steam, as the issue is due to a "corrupt mesh file." Also notable: The head-turning bug here was highlighted two days ago in a blog post by one of the game's producers, who identified it as a known bug that was "eradicated" prior to the game's official release.
