I need help with a custom modpack i made on curseforge, it is version 1.20.1, and is a gun sentered modpack. i was trying to find a specific vehicle mod i remembered from an old pack i played, called superb warfare. i tried out other vehihicle mods before that, called immersive vehicles. after i dleleted it from the pack it constantly gave me a warning that MTG started without a content pack, and that there would be no vehicles, exept superb warfare worked just fine, so now im stuck and dont know how to remove it
