Forum:My stores don't change

None of the stores update apart from my transactions Example: I buy all the stimpacks and shotshells from Moira. I go back to Moira several days later and there is no change in her items and her bottlecaps are the same as before. It's also like this with every other merchant I do business with.

I am playing the game on Xbox 360 and none of the other playthroughs have done this. I have deleted all my saves, cleared the HDD cache, and reinstalled the patch but it keeps happening
