I believe an enemy clan from another kingdom is using 2 towns as rotating doorways...as in they have a bunch of towns with piece shields up, and 2 with none, they allow these two towns to be attacked with no worries, but they send troops in and out as well as convoys. All resources yielded go into the destroyed town and are then sent to shielded towns via convoy or reinforcements....I need to try and eliminate these towns. Any ideas?
