I was recently trying to fix a weighting issue in Moodle and forced the weight to equal 25 on 5 assignments in a single category (aka the total weight would have been 125). One of the grades was an extra credit grade. Unfortunately, this seems to have made the gradebook inaccessible. When I try to access it through the "Gradebook setup" button, it hangs before timing out, and when I attempted to look at an assignment to see how it was effected, it gave me this error:
"Exception - Call to a member function get_name() on boolean"
Any thoughts on how to get back into the gradebook and fix it without losing all the grades? Currently running Moodle 3.2.6.
