The faulty patch recently released for Fallout: New Vegas has been fixed for the English version of the game. The v1.3 patch - originally released Thursday - was defective and some players experienced problems loading saved games, as well as freezing screens. A patch (for the broken patch) is now available for the English version of the game and will be presented to you upon booting up the game. This problem was fixed fairly quickly considering the original patch was released Thursday, and the problem was remedied on Saturday. Bethesda has released an official statement regarding the new patch:
“Regarding the Xbox 360 update, the new game update that fixes the game save issue is now live for the English version of the game. We’ll let you know asap when it’s available for other territories. Thank you for your patience on this matter.”
