Fixed :) It was a typo on the 'Quest Number' on the actual quest's page, sorry about that D: The list on this current page we're talking on, is just a displayed list using some code to retrieve the quest name, level, NPC giver and location, and reward information. You can't actually edit any of that information from here, you need to head to the quest's page itself to do any of that..
And speaking of editing, don't worry about breaking/ruining a page! :D *ANYTHING* you do can easily be fixed in a click or two! There are only a couple of files that can really throw a wrench into the works, and they should all be protected/admin-only, so you don't need to worry :) Even if you completely delete an entire page out of spite, as soon as an admin sees it they can hit 1 button to bring everything back!
