Serendipity it's not the same person.

She could well be eating from her stash, have you checked to see how much she has hidden away, the amount they hoard does vary a lot from one to another but it's good to have an idea of what's there if something like this happens.
Has she not touched the food at all? That would be a bit unusual, I'm guessing you haven't changed her diet or anything?
Keep a close eye on her just to be sure she can eat ok.
