I have a problem and it is advanced in the main story after doing the Chinese mafia start missions, I see that what follows on the phone is that I have to go to high school but nothing happens, doing a little research is supposed to be when Warren is waiting for you outside the school to take you to the shooting class but in my case does not appear and according to the time range is from 13:00 -17:00. Does anyone know if I have to do something else? It's already the second time I start the game :c
