Hi
i'm stuck in chapter 4. i've just completed both the jock and nerd challenge but now there's nothing to do. no more tasks, despite the paper boy thing. is this a glitch?

happenes to me many times, maybe thats it.. or maybe u need more money, go to bed or go 2 class then try it. click select then r1 then tasks

No glitch. Missions are only avalible at certian times. Just wait and something will eventually come up.

Just like afternoon classes you have afternoon missions just like Tromonator13 said 2 you, just need 2 w8
