Whenever I launch the game, I get this crash (https://pastebin.com/0JPvJUDU). It only happens after I build my .jar and put it in my mods folder; everything works fine when I run the mod in IntelliJ.
Here are my main class (https://pastebin.com/j8Pxu2qs) and model class (https://pastebin.com/Gi0j3KF1) if that helps.
