OK, it has been started. Turn sent to Persia and SoD moved to Herat. However, there might be a problem with that since I guess the SoD has too many units. I was unable to scroll down to the end of the stack to see the control menu neither did I keep track of how many units were moved there. I hope there are more experienced players who know if some of these units will be lost during saving of the game. If yes, it might be needed to replay the turn probably. IIRC, game allows about 255 units on a single tile but I'm not sure. May be less, may be more.
