I got 100% but I don't have the achievement for getting 100% completion. So what do I do? I have tried just walking around, redoing bike/go-kart missions, paper route/lawn mowing, failing and passing classes, but none of this worked, not even restarting console. Does anybody have any suggestions or know how to solve this? Something similar also happened for completing 3 and 6 classes, as i don't have those achievements but have the one for 9 classes completed.....
EDIT: FINALLY! After about 30 minutes of doing nothing it finally unlocked, wow.
