So Iím at the part in the game where Cartman allows you to pick a 4th a class and I chose martial arts. However after finishing the backstory again using the new martial arts attacks, I donít have a 4th class. I just have my first 3. When I go to the power screen it just shows my 3 classes and idk whatís up. Did I mess something up? I guess I could back and talk to Cartman but I think I may be at the end of the game. Any help would be appreciated (no spoilers please)
