I have some stuff I need to take off here, so I will be unable to give a long response here for a few more hours. The short summary of my thoughts are that I am unsure what my own opinion is. I definitely feel we are entitled to get the stone immediately, but I also am very much in agreement with the sentiment that we should not push our luck. A possibility is to offer RB the loan of 1-2 of our workers for 1-2 turns to hook up the stone near Starfall (their new city) so they get it quicker in exchange for them giving us stone 4-6 turns from now. That way they will only be without stone themselves for 2-3 turns, which is exactly what we need to chop TGW.
