That number in the link wasn't updated until someone looked at that page.

The number in the link only gets updated when someone register after an invitation or when someone looks at that page. So the ones invited before I implented this, wasn't counted until you looked at that page.

So the only ones with an errorous links are old people that have invited others, but has an invitation-list-page that no one has looked at. I don't think there is anyoneof these members left now.
