So I just tried to make a 15 furnace auto smelter from this video: https://www.youtube.com/watch?v=acKnjrKSqzI
but the problem is that the hoppers that are supposed to put the fuel and items in the smelters aren't fully delivering the items it goes a little ways then the items just get stuck. here's some pictures and my world DL
