I tried to use both the coke oven and the blast furnace on 2 separate mod packs and they wont light or activate. For the blast furnace, I load it with charcoal and iron and the light never turns on and makes steel for me. The same thing happens with the coke oven when I put coal in it. I am having this issue on a server, as I tested it on a single player world and it works. I do not know why the server is having issues for me with this.
