Explicitly, Wikia's achievements only count from the moment they're turned on. I checked, but there's nothing we can do about backdating. Consider it achievements for 2017 ;)

On an aside, we currently use Wikia standard achievements, but they're fully customizable so if you have any ideas for others, it may be something we can get to.
