There is something which I fail to understand and that is why on earth Messages in a Bottle do not stack with each other. Yes, they can become an SoS or an Ancient SoS but that happens "after" one double clicks them. Before then, they are all the same one thing as the RNG comes into play only the instant one double clicks the bottle, not before. Therefore, MiBs sound to me all one same, exact thing. Why they do not stack with each other then ??
