Couple of things are super frustrating: 1. The guards run away from the invaders 100% of the time. 2. It doesn't allow me to remove the ads. I've tried selecting it multiple times. Really would like the ad punishment to stop. 3. My shipyard and trading dock are useless. They do absolutely nothing. I've built ships for expeditions and staffed the shipyard. Does nothing. The trading dock doesn't even let me staff it. Totally useless. I would give this game 5 stars but too many issues.
