Hello guys, I've been having a problem with the Dead Money DLC. Last part of the game where I'm supposed to go down and "discover" the vault, I have christine say the password (and tried it another time myself but with same result), the quest shows I have to Discover the vault now. so I go down the elevator where you find the door that leads inside the vault... The thing is, the door is not opening! It gives me a quest log saying "Discover The secrets of Sierra Madre's Vault Chamber" but when I try to go through the door it does not open !
Any ideas? thanks !
