Random encounter - trader

[Kaytila]

So, I meet this trader in the wild - well away from any settlement.
why is he there?
imagine pirates: you did not see trade ships near the bermuda triangle, but next to the antilles where there was actual trade.

In addition to that -if you ask for towns, normally, they dont know any. So how are they trading if they dont have any partners?

What is more: so you ask him questions, then click on trade. when you return from trade, the last thing you asked is still showing.
I personally would just remove the dialog before opening the trade window.
