Let me make sure I understand this: You've done nothing but criticize me and my game for the past 6 months. You've upvoted damn near every bad review that my game has received on this site. You were so critical, I even singled you out and specifically told you not to play V1.0 when it was completed. You fanned the flames of hate that my game got after the original release. And now you want me to go back and change the coding of my game to suit the needs of a mod that someone else made? All so it eliminates a key character attribute from a main character of the game and changes the story from the way I intended? Did I get that right?
I have no idea who made the "Nikki Mod" or how it works or why doesn't work with the completed game. And honestly, I don't care. It's not my mod. And I wouldn't go back and change my coding for any mod. The point of mods is to modify the base game. The base game doesn't modify itself to suit the modifiers. That'd be backwards and makes zero sense. Like
goobdoob said - ask the person that made the mod. Or learn renpy and create the a the mod yourself - it shouldn't be difficult for a smart individual like yourself to do that.
