PROGRAM: RPG MAKER XPIssue(s) with: Tons of Addons Different Difficulties issue
PROBLEM: I have another mode set up to be played after the game is completed, It unlocks the mode. The mode is then selected from the title screen We'll call it battle mode. I'm not having an immediate problem setting up getting to the mode or the seperate set of maps. Its just that when an enemy goes to attack I get this error:
which then takes me to this line of coding in TOA pt 2
Line 3475: self.damage = self.damage * $game_system.enemy_rate / 100
WHAT I AM ASKING: Is there a way around this problem or would it require more scripting knowledge than I'm aware of? I think it might be because it doesn't know which difficulty to turn to or use in this case and if I cut off different difficulties then it works just fine. But then that makes it so that it can't be used in the main portion of my game. And I need that for the actual main part of my game.
So to make it short I'm not sure if there is a way around this or not. I have very very little scripting knowledge and I don't want to hack up TOA without knowing what I'm doing exactly.

because then that'd just be a disaster in itself. I was hoping that maybe one of you talented scripters on here would be able to assist me in said issue. Or help me to counter it or something?

-Character Select
