There is a bug with advanced engineering and the reduced resource cost of forges and steel. When taking the tier 3-5 of the perk you can not craft all your available iron and steel. When switching between the tier 4 and 5 of the perk with the intellect mod in helmet you can craft the same amount of steel but with the tier 5 perk there is more of the resources left in the forge.
The poi is called house_old_gambrel_03 "Bobs boars and Carls corn". If you dig the sand block in front of the metal door of the cage into the loot room, (Where you exit when completed the poi correctly), The door collapses and it is easy to get to the main loot.
