For some reason BreadCrumbs omits certain page titles. It seems that when I go to a page that I was recently on, but have visited enough pages since to push it off of the Breadcrumbs list, when I go back it will not show the page. I do not know if this is a problem with the caching of the BreadCrumbs or what. Could it have to do with how often the cache is invalidated and the length of the BreadCrumbs shown not being the same? If the page is far enough back, it will show up in the BreadCrumbs however.
