It happens with any class, i'm using the start new game without tutorial button. And from the previous update, I couldn't get pass the 2nd fighting scene. It just didn't load.
Edit: So today I had the chance to play the game with the tutorial and it works. I can pick a class and fight, so if anyone has a problem with that, just re-do your game by playing from the begining but without skipping the tutorial.
P.S. It works with every class.
