I'm playing the 1756-63 campaign as Austria and the Russians have entered the war. However the large force which includes Apraxin, seems stuck in the Wierzbolow region where it spawned. A few turns have passed (it's now 1757 Early Sept) and it's still impossible to move any of the Russian forces from Wierzbolow. I can't move them back to either of the Russian off-board zones, nor into Poland (I get the message about Polish territory being out of bounds), nor into any adjacent Prussian-controlled regions, even if I turn them Austrian with some of the other, free-moving Russian units. Wierzbolow itself is showing as 100% Polish control and "cannot be entered".
Is this right? Is there some event that will eventually fire and release the Russian forces?
