you could technically just put them back in, but they were removed for a reason
.. okay, some reason. I honestly can't recall exactly :laugh:
more accurately, it's pending an eventual re-overhaul to make it more streamlined (ie. preserve its traditional complexity while reducing the aggregate amount of buildings for the sake of performance)
Where could I find a copy of the old buildings file? They're more interesting than the vanilla buildings and I don't mind a performance hit
