After an early turn in the game, my option for Space Race just disappeared. Realignment, Event, Place Influence, and Coup were all available, but never Space Race throughout multiple turns. I played as USSR and before the space race option disappeared for me, I had played "Defectors" as a headline card. I didn't think it would allow me to do this, but it worked. I wonder if this triggered a bug? The game number I was playing was #1277878. I tried to access Space Race on multiple turns, at various times during the turn, but it was never even given as an option.
Thanks so much,
