Academy Course "Incomplete"

I completed every assignment for the WPMU Dev Academy Multisite Masterclass. I double-checked that my final assignment was submitted the week it was supposed to be "graded". Now in "My Courses" it shows that the course is "Incompleted". I'd like to know why. When I click on the "Incompleted" "button" I just get taken to a page that shows the course is unavailable. This isn't earth shattering, but I completed that course and I don't like that it shows that I didn't and that I have no way of finding out why.
