I don't know if its just me but I'm having a hard time moding the game, no matter which way I do it. I drag and drop into the mods folder but doesn't work.
probably just you. if you unzipped a mod make sure to get the inner folder out of the unzipped one. then try dropping the inner folder into the mods folder. otherwise it won't work either way. also, if you already did this and it didn't work, make sure you are using a mod for exactly this version of the game.
hope that helps :3
