This Github repo has been created for the sole reason to track updates, issues and feature requests for the HNG Pack avaliable on Curseforge (https://www.curseforge.com/minecraft/modpacks/hng-pack)
If you find a bug, I would request (where possible) that you first work out what mod(s) are causing said bug and raise the issue on the relevant mod(s) Github/Forum post. As expected I am unable to fix any bugs that are within specific mods that cannot be solved with a config file change.
