1. Fail to send shipment: when you click at a shipment, sometimes it won't send. You may need to click 2-3 times to ensure it, or you'll be in trouble when enemy comes and you find that you didn't really sent 2 cannons.
2. Fattened cows/sheep will ESCAPE when your vills try to kill them, just like buffalo.
3. (Maybe not a bug?) You can do nothing when you're searching games. If you try to check profiles, ladders, the search just ends.
4. Ladder page: you can only check the 1st and 3rd page on it. Even a primary school student won't make these kind of mistakes
