Fallout: New Vegas 18.104.22.1688 was released on October 20, 2010 for the PC and PS3, with Xbox 360 version following at a later date. It fixes around 200+ quest and scripting-related bugs in the game. It is automatically downloaded via Steam and Playstation® Network.
Patch 1.01 is stated to fix around 300+ quest and script errors/bugs as follows. According to Senior Producer Jason Bergman, Bethesda didn't provide a list of included fixes and changes because a complete change list would be the size of a novel.
- Fix 1 - After implementing the patch, the abandoned Brotherhood of Steel bunker becomes locked, requiring you to use a non-existent key in order to open it. This prevents you from obtaining the skill book Dean's Electronics located inside. The only workaround is to remove the patch, get the book and then reinstall the patch.
