Completion Status is not working

I have found that even after completing quizzes, etc that the course never completes and is stuck at 67%: http://puu.sh/ho5pv/960e670253.png

I am running stock Wordpress with just CoursePress and the CoursePress theme. I have found that CoursePress freezes my site at 100% CPU from time to time and never loads until I restart my server. I have duplicated this on a Bitnami Wordpress VM and on a live web install.
