Bugs
28-03-2021 : Metal mined from a Metal Ore Mine is called metal, but also when melted it is still called metal.

28-03-2021 : Charcoal is assumed to be high heat, but this is not shown in the tooltip.

28-03-2021 : Dragging an entire stack (shift + drag) of raw metal into the forge, makes the items disappear, adding one later shows all the items that used to be in the forge again. This bug occurred after beforehand a stack was dragged in successfully and dragged out again
