We always said that there would not be a set limit on trade in this game, but any trade deemed impractical would be stopped. We need to start looking at some of the trade in this game. Imperium Scotiae is trading with both Iberian nations - does that sound realistic for the medieval period? They are in pretty much the furthest away part of Russia, and don't even have access to the Baltic.
That was just an example, I'm sure there are other trades which are equally ridiculous.
