So i now have all the great people, except the great builder, Gilgamesh. So at one single player game the indians had him ,i captured their city and got Gilgamesh. But when the game ended, i didn`t get Gilgamesh and the achievement. I`ve also tried to capture him using spies but that does not help either. So i can only get him to my hall of glory by getting him myself, not capturing him from the enemies?
