Custom Taxonomy/Post Type permalink rewrite

I am trying to rewrite my permalinks to make them flow better, but the permalinks keep throwing a 404 not found.

Original permalink structure:

Re-written permalink structure:

example.com/{'game' taxonomy}/chapter 1

Rewrite code (in functions.php)

function custom_post_link($post_link, $id = 0)
{
  $post = get_post($id);

  if(!is_object($post) || $post->post_type != 'woo_video')
  {
    return $post_link;
  }
  $client = 'video';

  if($terms = wp_get_object_terms($post->ID, 'game'))
  {
    $client = $terms[0]->slug;
    return str_replace('%gameTax%', $client, $post_link);
  }

  return $post_link;
}

add_filter('post_type_link', 'custom_post_link', 1, 3);

The links are re-written properly, but when I visit each link, it throws a 404.
