That line is already set in the latest ddraw. But, let's make sure we are talking about the right thing and there are bugs involved:
Regarding the BoS Bunker: I said there were conditions involved. That means you can't just go in. Quests and all, ya know? Talk to the people around the elevator. One of them might have something useful to say. If you have done the quest and it doesn't work, then there is a problem. Have you done what was asked of you?
Regarding Vault 23: Are you actually talking about the elevator inside and not just the entrance where the shack is? If you are referring to the inside elevator, then like I said, you have to do something to get it working. If it still doesn't work after you have fixed the elevator, then yes, there is a bug. Have you fixed the elevator?
