I am a district-based coach and created a course with 30+ New Quizzes so they can copy them into their courses to use with students. The other teachers were added as teachers into the course so they could copy them. It was working, but over the last few weeks, we keep getting an error message - see attachment. Even if I try to duplicate the quiz in the same course, I get the same error. Is anyone else having an issue with copying New Quizzes? 

We tested with Classic Quizzes and those are copying just fine. We do not want to convert our New Quizzes to Classic because we need the stimulus and the Outcome Mastery by item, not by overall quiz.
