I set my course's extra credit assignment points to zero and the extra credit assignment immediately disappeared. I can't see it in the Gradebook or in the list of assignments. When I search for it, it does not appear. I have student assignments in there waiting to be scored.
I did not delete them, so using the /undelete function did not uncover the assignments. I don't know where they went or how to retrieve them. Please help if you can!
