I am seeing several instances of learners who have submitted their assignment on time, yet on the grading summary screen their attempt is showing as overdue:
This is baffling as other students' attempts of the same assignment activity are behaving as expected. I have seen this occur in several different courses, seemingly at random over the last two months or so. We did have an outage in March and had to restore from backups - could there be some data missing or corrupt that might cause this?
Any thoughts or suggestions most welcome.
