Can someone identify what in these recent updates caused this template to cease functioning? While I'm hoping that it's an unexpected bug with the update that can be fixed on Wikia's end, odds are we're going to have to completely ditch this template. It function ed  similar to the tabber extension, except that it loaded properly rather than displaying all the items first and then fixing itself at the end of the page load. (It also looked a whole lot prettier :P)
