Bethesda believes it has fixed the issues from the recent Fallout New Vegas patch (1.3) which froze game saves and made other parts of the game unplayable. The update was only for English versions of the game due to Bethesda still working on other language versions for their patch.
The new patch for the 1.3 update unfreezes game saves while keeping the stuff the previous patch fixed unchanged.
Bethesda noticed the issue with the patch after a few users complained about the save bug and warned everyone to not update the patch. They also warned Microsoft to not make the previous update mandatory hours after it had occurred.
This also isn't the first time Bethesda has had issues with faulty patches involving saves either on the Fallout or Oblivion series due to the engine itself being very buggy especially after changes are made.
