It is impossible to set up a decent trade route with so little demand. Where I am, the best route I can do right now is a Gold/Silver run from a refinery that is mysteriously selling both very low (that trip makes me 20k), then taking NOTHING back there and repeating. Seriously, taking nothing back is optimal. Surely it should be better than this? But this is the only way I can get more than 200 cr profit per tonne. Pretty depressing. But have the devs acknowledged this or is this what it's going to be?
