Nowhere in the rulebook does it say that buildings can count for multiple objectives. In fact, it explicitly says that each component can only be used for one objective, and the tooltip for each objective in the game says the same thing. (See screenshot.) And yet the tutorial explicitly says that buildings are an exception to the rule. Why? Where does it say that in the rulebook? And why doesn't the tooltip in game mention that?
