Hi,

I am using Version 2.3.1 of your mod and the furnace generator produces RF as it should, but does not use up any fuel. Supplying it with one piece of Coal/Charcoal lets it run forever.
The Upgrades increase the output as they should.
The Liquid Generator uses up fuel as it should

Best regards!

Wow I can't believe I missed that. We just rewrote all machines and I knew I'd miss something
