OK so you know the bobble heads???? well i started collecting them and i have most of them but i was borrowing the game from a friend and i wanted to get all of them before i had to buy the game, so i looked up the locations and 1 of them is in the vault!!!! now i know you are all about to say "dont worry you go back to the vault later in a quest" well i already did that quest!!!!!!! so what do i do????? is there like a cheat or something i can use????
