Quiz module: I wrote a numerical question with two possible answers. The question works. Then I deleteted the second answer with the feedback and gave a general feedback. As I try to save the question I get the error message: "One of the answers you entered was not a valid number."
But all the fields of the second answer are empty. Does anyone know this bug. Is there a workaround?
