US played Grain Sales to Soviets, pulling Missile Envy from the Soviets hand, which US then used as event. This pulled Flower Power from Soviet hand. Soviets *should* have been forced to use 2 ops from Missile Envy next AR, but as Soviet player, I was not able to do so.
In fact, I was not able to play any of my remaining 3 cards, no options for playing events, placing influence, etc. Game is stuck on Soviet player unable to advance the game state.
