I haven't figured out how to fix this yet, and the way to stop the timer is to keep jumping until it stops. Occasionally it will tell you that you have beaten the course, however, the timer will keep running. There is a bug at the end of the course to stop the timer.There are 1 block wide end portals above the course for extra lighting (there's no way you could enter the end through them because they have been surrounded by barrier blocks). If you notice any particle effects above the course while you are running, do not worry.
