Basicly what the title says, im always loosing rep when using auto-trade routes. How come?

All town rep are sky-rocketing upward yet im loosing internation reputation, why?

Usually it's because your buying supplies that are in short supply.

ie. you goto a town that does not produce fish but you buy up all their stock. The result of that is you lose reputation. What you want to do is buy goods from towns that manufacture the goods and only sell in places that don't produce them.

Now, in saying that I still don't have PR3 but the other PR's and Patrician work that way so I'd image it's the same.

I just realised there is a normal decay taking place, if i dont keep doing these *nation* mission it slowly goes down no matter what, even when manualy trading. Speaking of wich, warehouse doesnt have the option to auto-buy wtf???
