So FastCraft. May I use it for my clunky laggy FTB modpack. I am new to this in fact It is just minecraft that I am not new to. mods, packs ,and a list of a lot more asking that you will grant my permission, I will not use config in this modpack at all including your mod, Other than biomes o, plenty if I am aloud. My pack is ConnectPack aka Big Bird.
