Plutonium

Maybe because it's a folder inside a folder?? Idk if you understand what i meant, like i just got that problem, so i just put the mod files in one file instead of a folder inside a folder let's say reimagined (mods/zm_reimagined/mod files instead of mods/zm_reimagined/zm_reimagined/mod files) im sorry if you don't understand or if it won't help you but i give it a try
