Arc Furnace Automation/5/en
From Unofficial Stationeers Wiki
So we just want the Arc Furnace to activate whenever content is put in. You might thing you can just bind its "has input" (ImportQuantity) property to its Activate property, but sadly if you're piping content with a chute this will not work. The exact reason results from some internal game mechanisms but the gist is that the value needs to be updated after the furnace has turned off (and ImportQuantity updates slightly before that), so that's why we're adding Activate to the value.
