So, whenever you win an online battle in this game, you gain a certain amount of battle points.

As you can see, from this battle, I gained 700 battle points as a reward and now have 700 battle points in total.
However, I've tried multiple ways to hack the amount of battle points I have in total AND the reward amount, but to no success. I've tried changing the total amount of battle points I've had to a large amount, but it wouldn't save and return back to the previous amount. And when I edit the reward value, it also doesn't work and returns to the original amount.
