This should probably be a cross post with gradebook, but I'll start here. Tell me if anyone has seen this or what you think. We are using Moodle 3.0.3.
We have our forums set-up to be an average of ratings. If the grade is set in the forum and we go to the main gradebook to alter a grade, manually over ride one, it will override the one grade but then will knock out everyone else's grades to zeros. Super bizarre...anyone see anything like this before?
