I have recently created a mudpack with a couple of mods to run on a self hosted server for me and some friends. however, I cannot get the mudpack to open up in forge, it simply opens up in vanilla 1.12.2
here is my mudpack : https://www.technicpack.net/modpack/modpack-for-the-simps.1672558
please excuse the name lol, but someone please tell me what I did wrong.
