I attacked with tanks from Archangel and Russia (Moscow) into Karelia. After some really bad dice results I attempted to retreat. The game offered my Archangel as the destination. After I clicked on it to select it I received a diamond with a flag in the “Retreat” text over Archangel and a notice to click on the red ball with the arrow to finish my retreat. The text over the red ball with the arrow even said “Finish Retreat”. However, clicking on the indicated icon did nothing. Nothing I tried would get my units to retreat. I had to keep attacking until all my units were killed to gat past this point in the game.
If this is a bug, where do I report it?
