On the main course page, my little green guy in the lower left corner still has an empty crown and circle mouth face, even though I have 100% mastery, a 93% on the course challenge, and have completed all of the units. I feel like I'm ready to move on from this course, but I feel bad leaving the guy behind before giving him a golden crown and smiley face. Do I have to get 100% on everything, or does this particular instance of the crown guy never get a yellow crown and smiley face? (Annotated screenshot attached)
