On the east of that map,as in all the enemy tanks,guns etc,that are on that flank must be destroyed,if you just capture anything on the eastern flank & use it,the game wont end,so anything you have captured from that flank you need to destroy completly.
Thanks, but I downloaded the 1.16 patch, and before it was the 1.13 patch, so that might have fixed it. It doesn't matter if I jack tanks now.
