There is no output on the furnaces so they can not be used with any other automation mods. Really upsetting as they would be great replacements furnaces for my automatic smelting system.

Forge 1.17.1

I had abandoned updates to 1.17.1 version as I thought no one else would use it to play with mods. I will release at least one last update, being a port of version 1.18.1, to fix this bug

Thank you very much :)
