I had something happening, where I am not sure if this was a bug or intended. When using the services of Vanderdecken (the shipwright) on the Isla Muerta (ship repair), I teleported directly on deck, ready to leave shore ..... only to realize that my ship was in the Kingston Harbor. So my ship basically teleported from the Isla Muerta to Jamaica, which actually was really conveniant for me. But it doesn't seem right. Or is it?
