We are on Moodle 2.3.3+. A Tutor (our term for "editingteacher") has recently reported that he is unable to view submissions for a particular assignment (the grading table page shows "Nothing to display"). He is able to view submissions for assignments on other courses, and another tutor on the same course is able to view submissions for this assignment. Other permissions appear to function correctly, and he can even edit settings for this assignment.
Has anyone else seen this, and any suggestions that could point us towards a solution?
