Just a bit curious, and not sure if this is a bug or not, but has anyone else had a problem getting the vault suits for Sarah Weintraub in Vault 21?

I talk to her about the vault gear she sells, do the two speech options (can't do the barter option though), and agree to bring her back any vault suits I find. The problem is, after I bring her any number of them the first time (doesn't matter if I bring her 1 suit, or 15), the next time I speak to her, I don't have the option of giving her any more, even though she says she wants me to keep finding them. Has anyone else had this problem?

Oh, also, is their any way to get Sarah to let you into her room, that doesn't require lock-picking or pickpocketing the key from her?
