On the search pages (as well as any forum page that shows highlights), the highlights shown depends on the value of the "start" query in the URL. So, for example, if the query is start=30, the highlights shown will start with the 31st one (currently Burning Heaven from January 2012) instead of the newest one. This causes the wrong highlights to be shown on the search pages if the user is viewing any page other than page 1.

This happens when there are multiple pages of threads to browse through, as well. On the "unread replies" page, if I go to the second page, the first announcement is this one (incidentally, it's the first announcement on the second page in the announcements board).

because Yarn mentioned it here.  It also happens when clicking on previous pages of private messages.
