Basically, I made a modpack so that my friends and I can use optifine 1.13.2 on technic and then add some other mods as needed later. For the most part, I have followed a detailed guide on making a forge modpack and made sure to name the forge file in the bin folder "modpack.jar" and not "modpack.jar.jar" as I have seen other people do. The problem is that it loads vanilla minecraft even though I have forge in the modpack. Here is a link to the modpack so you can see if I am missing anything crucial: https://www.technicpack.net/modpack/optifine-1132-vanilla.1416127
Thank you for any help/advice!
