If I put a GT debug scanner in a basic electric furnace, i get the not enough power symbol. And the machine does nothing at all.
If I remove the debug scanner though, the furnace smelts 4 items before going completely out of power.
That is really weird. If the machine does not work with 32V infinite energy, I would expect the machine to NOT work if I remove the power source in question.
Is this a feature of some kind?
