With Yuoki mods enabled, placing a blueprint with furnaces will set them to request fuel cells from yuoki's mods, even if player has no yuoki fuel cells available, this results in furnaces placed not receiving fuel from bots (removing yuoki results in them getting coal if available, or wood if no coal is in player's inventory), but with yuoki installed, it doesn't function right.
not sure what bit of code from AutoFill or Yuoki's mods is causing this behaviour, but i thought i'd let ya know. if furnaces are placed by hand, they of course get fuel (usually coal) as normal....this interaction only seems to occur from placing down blueprints.
