The High Oven is running off one redstone, one gunpowder, one sand
can run as much iron as i want through the high oven
once i break the controller the redstone gunpowder and sand is gone, but i still have any steel i poured out in the mean time

also the controller will not respond to a redstone signal once it gets charcoal its on

it should be fixed with the latest version on Jenkins.

To be tested

I can confirm, it has been fixed by zmaster587's commit

About the charcoal: it will keep burning the piece of fuel it was consuming but won't consume any other and will stop getting heat once that's done
