Not sure if it's a problem with Forge or with the mod, but the "Config" button does not allow me to configure the mod.
If I am simply missing something, please advise.
Mod version 1.5.61

Hey sorry for the late reply. Essentially the config button doesn't work in forge. Its been planned to implement it in forge. You can edit the config in minecraft_dir/config/vanillatweaks.toml
