Something similar happened to my German GC'36 game after the Bitter Peace. I was still at war with two of the four minors in the Comintern, but at peace with the Soviets and its two puppets.
Good job so far. The Polish forces may not survive long though - they should be out of the SU supply network, and stuck without new supplies as they have no connections to any ports.
