[CoursePress Pro] CoursePress – Unit Quiz Change Bug – No Certificate Issued

When you change a unit quiz and or add more units to a live course, the entire course becomes broken. The result is that students only get the pre-completion page . No certificate can be issued and student stuck in ongoing status. Only method of recourse is to rebuild the course. This is not a good solutions with 12K students.
