Thank you for the notification. I am a bit bogged down with work this week, but I have an idea where these are coming from... It seems many of them are either:

1) Exercises that were on KA, written by us, removed from KA, and thus are orphaned. Since they are under no real missions, I have removed the links to the missions they used to be under, which is probably what is giving them "dead-end" status. These will generally have the "Previous math exercises" category.

2) Exercises that are on KA, but do not fall under Math Missions, and thus are orphaned. I have been labeling them with "Non-masterable math exercises" as a category.

I will think of a fix for these and provide some links in this message a little bit later. Thank you for drawing my attention to the matter.
