Hi Myenemy,
what version of the plugin and rpg maker do you use?
Best regards,

Hey Myenemy,
I think I figured out the reason for the crash. I just released an update that should get rid of the crash. Alternatively, you could check if you have classes that have trees assigned that don't exists. Remove the skilltree notetags for these classes and the game should start.
Best regards,
Felski
