Ahhh, I understand. Keeba is not designed to delete assignments once they are deleted from the school website. The reason for this is that many teachers will periodically remove past assignments (e.g. from one month to the next — not talking about from year-to-year) from the website, and a number of students (myself included) like to view all the assignments in a class to prepare for an exam. For example, to prepare for my calculus midterm last week, I clicked “show all assignments” in that course and I could then see all of the assignments I had completed in that course, and I could then review and redo them as practice.
Your situation is of course an interesting and legitimate caveat of Keeba’s current behavior in this regard. Perhaps a good compromise would be that when Keeba sees that an assignment has been deleted by a teacher, if the assignment’s due date has not yet passed (i.e. it is due ‘today’ or at some time in the future), Keeba would then delete the assignment from the students’ page. That would
