Kostya, you probably already understand that you are wrong, so why are you insisting? What changes to the rules regarding mutual consent are you talking about when it ALREADY EXISTS IN THE RULES? What are you talking about? :confused:
Here is an example from a real game, why do I need to know that there is no cartographer.
I'm running around the treasure, there's some kind of goal, I don't remember what, it doesn't matter. I urgently need money for something, and there is none anywhere. I carefully examine the edges of the darkness around me and find a very small piece of the top of something, it looks like a Naga bank, but I might be wrong, and turning back means losing momentum. I went through all the buildings in my mind, decided that it was either a bank or a cartographer. I don't remember if I turned back then, but I remember that I was very doubtful.
