Yes, coin would have been easier, but #24 needs 400k wolfram and 85 trains only hauls 170k on my station and #23 is send 1.5 billion coin anyways so I think I made the right call. My wolfram is delivered. The coins will have to be sent, it's all good. I have millions of plastic, marble ,carbon, and wires to send in the meantime. But your right Richard, probably should just send something and hope for the best and be done with it.. I think of all the earlier contracts on the basic contractors that I send 100's of empty trains to complete . Plus I'll get that Zhosa to play with, 95 gems, and a good building now, rather than could be much later.
