I think this is probably an isolated occurrence: Just started a game and placed my Capital near both a Stone and a Marble resource. I go Calendar early on, thanks to an ancient ruin. But when I built Quarries on both the Stone and Marble resources, I did NOT get a Stoneworks available in the available buildings list. Haven't a clue as to why not, but 50 turns later it's still not appearing.
