Sorry for error with support from a city,I'm idiot,sure can make support from a city INSIDE or pressing 'h' outside,in the city tile
). Hurry hurry my bad style...
If a city have max 2 trade routes,that NONE van will make 2 new trade routes but exactly how I wrote,inside of that city,city X to city X +1 trade,city X to city X +1 trade.For a city having 2 trade routes before to send NONE van in city,an 'external' route is eliminated to make 2 new routes inside.
I maked other tests,with 2 new van these inside routes will disappear.Is strange,but that's it.
I saw here a post about food vans,how can eliminate a food route,in double sense maybe,I don't remember.
Anyway,I will send the save with that van for GOTM181,I want to use with home city normally home city,Xinjian,to be verified if is from that city.Before to eliminate Chinese,most cities were investigated with spies,to see if loose engineers bribing cities,so more engi were bribed before the cities,too other units,cavalry,etc.
If you want to see that 'nice ' van before submitting,I will send you a link from a storage site with a save private message.
