hook_uc_checkout_complete shows [order_status] => pending

Link to issue: https://github.com/backdrop-contrib/ubercart/issues/446

Hi, in hook_uc_checkout_complete($order, $account), when I look at the output of $order, it shows [order_status] => pending, and not completed. Also, when I look at the output of $account, it doesn't show the role that was included with part of the purchase(uc_roles). How do I get to the data after the order is officially completed and the payment has gone through?
Thanks.
