Hero skill tree.

This is most likely a case of the program malfunctioning. It's possible that the delays set within the program are insufficient to allow the game to load properly. This depends on the processor's speed. We need to find a way to resolve this, perhaps by adding a manual delay setting, but this isn't ideal for the end-user. We need to explore other options. Tell me, does the program work normally for you, even if you ignore the screenshots? Does it consistently level up the hero repeatedly by reloading the save, or does it suddenly stop at some point?
