Multifield & subfields not set on programatically node creation.

This is the function for saving the new imported node.

/*
 * Helper function for bulk creating Brand nodes
 */
function _patchwork_facebook_create_brand_nodes($new_brands, $uid) {

  foreach ($new_brands as $page) {

    $node = new stdClass();
    $node->type = "brand";
    $node->title = check_plain(str_replace("'", "", $page->name));
    $node->language = LANGUAGE_NONE;

    node_object_prepare($node);
    $node->uid = 0; // Set anonymous user as creator

    $node->field_facebook_page_unique_id[$node->language][0]['value'] = check_plain($page->id);

    if (isset($page->username)) {
      $node->field_facebook_id[$node->language][0]['value'] = check_plain($page->username);
      // Set the tax-term for the Facebook Username
      $node->field_facebook_username_term[$node->language][0]['target_id'] = _patchwork_facebook_get_term_id_by_name($page->username, $vocabulary = 5); // 'Facebook Usernames' vocabulary
    }
    if (isset($page->category)) {
      // Set the tax-term for the Facebook Page category.
      $node->field_category_term[LANGUAGE_NONE][0]['target_id'] = _patchwork_facebook_get_term_id_by_name($page->category, $vocabulary = 7); // 'Categories' vocabulary
    }

    if (isset($page->likes)) {
      $node->field_brand_fans_count[$node->language][0]['value'] = $page->likes;
    }
    if (isset($page->cover->source)) {
      $node->field_cover_picture[$node->language][0]['value'] = check_plain($page->cover->source);
    }
    if (isset($page->picture->data)) {
      $node->field_profile_picture[$node->language][0]['value'] = check_plain($page->picture->data->url);
    }

    // Set current user as Brand Admin.
    $node->field_brand_admins[$node->language][0]['target_id'] = $uid;

    $node = node_submit($node); // Prepare node for a submit

    dpm($node);
    var_dump($node);

    node_save($node);
  }
}

And this is the node-object just right before 'node_save', which creates the error:
