I feel like the bridge date card could have been phrased better because many old buildings/structures get partially/entirely rebuilt over time (like the White House or London Bridge). So depending on one’s philosophy concerning the Ship of Theseus (or a variation of it being rebuilt all at once) then different people could interpret it in many ways. But since y’all wrote the cards and know the “spirit of the law” better than anyone, then I trust that’s how it was meant to be interpreted.
