So according to the in-game stats I've done 21 missions. The last one I completed was the Carnival Date one with the prep girl. Looking at a few sites, it looks like the 22nd mission is "Race The Vale" but I can't seem to get it to come up. I've been doing classes and the odd job here and there for about 5 in-game days now, but still haven't seen it come up on my map. Is there something specific I have to do to unlock the mission? Or somewhere specific I have to go?
