Yes, this has happened to me on a few occasions, too. Usually, you know your upgrade has cleared because you receive a new ticket in the mail. But sometimes, you never get that ticket even though the upgrade has cleared. In such a case, go to MMB and use the "Resend ticket" function, or whatever the button reads. It will automatically send a new ticket to your email.
