I would assume that the following is a bug, if not then a lot of players are going to be unhappy:

In the pirates game, you can be sitting in the port and with just your half of the map and get ganked by someone with a full ship and 50 lvls above you. In addition, you lose your map piece. Please either make different mirrors of the game with lvl caps so the fighting is at least even or make it so you cannot be attacked with only one person on the ship.
