So I presume I have done everything correctly, 1st i extracted the same version of forge into the bin folder and renamed it modpack.jar then i put my mods and config in the root directory (outside the bin folder) then my custom files like custom main menu so forth, i zipped it up uploaded it to dropbox submitted it on Technic and then downloaded it and i have reinstalled it 5 times but it keeps loading vanilla minecraft its 1.12.2. Im very confused in i tired floping the minecraft and the modpack names around in the Technic directory but that just crashed the whole thing does anyone know a fix?
