I have encountered a problem when trading between Indian ports. I exported tea from my base Cochin to neutral Calcutta. When I sold my tea in Calcutta by dragging ten tons into the trading hub, I was payed for only 1 ton. This happened in other neutral ports, too. In my home port Bremen I get paid correctly when I drag 10 tons; so I am forced to sell my wares ton by ton in neutral Indian ports. What's up with that???
