Not having much luck getting this: latest game started 9 civs, 21 C-S , ended up with 24 sites+ 10 hidden sites, I got them ALL, got 9 C-S artifacts, but 2 were Vancouver, so score was 8/10. Best overall result was 10 artifacts, but 3 were Panama so 8/10 also. Tried quicksaving before making choice, but seems the artifact is already set in stone. Does anyone know WHEN the artifact is decided? When the dig starts? When the game starts? When the sites are exposed? Any hints how to get more C-S artifacts created??
