To be honest, I've never gone looking for this before, but I'm wondering if anyone can explain these logs. From first glance it looks like a student has been editing some other students' grades. However, if I check the grades history, shows no evidence of this. If I log in as the student, everything is normal and their permissions are fine. I don't think there is an issue, but it seems strange.

There is no record of the user role being changed either. Weird.
