Is there a way that the breadcrumb can be more accurate on a category page when a product is in more than one category? Right now, it tries to get the category id from querystring and CurrentItems, which both return 0, then from cached page views. That can cause an issue if the customer is bouncing around categories where the product is in more than one category, I think because the GetUserPageVisits does something with session? Are the page visits being added to the session in the correct order?

Sometimes it works, sometimes it doesn't work. Since pageviews are saved every minute, maybe the user was clicking through categories and products too fast and so the 1st category got picked up instead of the 2nd category the product was in? The client saw the wrong breadcrumb and I saw it also. Maybe customers won't see it since they will be moving slower? Just a theory.
