I've noticed this too, except that it is true for all Special pages I've tried to access. WantedPages, UnusedFiles, Log, WantedFIles... the list goes on. I've already contacted Wikia in the hope that it's a bug, although this leads me to believe it's intentional. It also messes with searching for normal pages. If I was to search for User:, unless highlighted the page I wanted it takes me direct to the search results page.

Oh, and you can no longer go to other wikis through the search bar either. w:c: attempts to do an internal search, rather than redirecting through central.
