I have a quiz with multiple choice questions where multiple answers are correct. The combined feedback options are for any correct response, partially correct responses, and incorrect. So, if A, B, and C are correct answers and D is an incorrect answer and the students checks all four, I would expect that they should get the partially correct feedback, because one of the choices selected was incorrect. But they get the any correct response feedback.
Maybe my expectations need adjustment...but does this seem weird to anyone else? Is this actually what should happen or is it a bug?
