The URL points to a course module which is invalid, so it cannot be uncleaner. But at this point, we already know the course or maybe even the section that it belongs to.
In those cases, we can redirect it to the closest known point.

hey can't find this page, maybe you can go to
course
section
search
and not a blind redirect to the top thing
