Forum:Major bug in game

Hi! I've accomplished many times the game. I've downloaded The Pitt, Anchorage and Broken Steel not long ago, and I've started a new game. This time I've choosen to find all the locations, and to do all the sidequests before I follow the storyline. I play as good, so I've done every quest the good way, so I've saved the 3 kids from Paradise Falls, than entered Little Lamplight to walk around. As exploring the map I went to the big chamber. I found the rear entrance to Vault 87 (that leads to the reactor room) that supposed to be locked down by a terminal and couldn't be open since the terminal wasn't powered - I mean it was like that before playing with the expansions. For my biggest surprise it wasn't locked this time. I mean the terminal wasn't powered, but the door wasn't locked and I could go in (without completing the "Follow his Tracks" - main quest). I was curios, so I went to find Flaweks (the friendly mutant), and I didn't have the conversation through the intercom as before. He wasn't happy to see me, just told me to sue... I freed him and let him get me the G.E.C.K, than as usual I was captured by the Enclave and I stopped playing at this part and started to think: I mean is this a bug, or is this possible, because of the expansions? If yes, it means that my father wasn't saved from the other Vault, he didn't die, I don't have access to the Brotherhood of Steel - (that means no big robot, no brotherhood help to get to the purifyer), but the enclave has set their base to the water purifyer... this sounds a bit off the main storyline. all that just because of an open door to Vault 87. (And no, i didn't use any type of cheat to open or to pass the door - I'm serious)

have you tried to start a new game and see if it happens again? if so then its a major bug. havoc131
