trading betrayal?

[sumthinelse]

Why is the human always the bad guy? I agreed to trade luxuries with Germany via a sea route. Then on the next turn it said that my source of spices (from Germany) had been cut off, and the program thought the sea route was not there, although I could see it clearly on the map.

Later, when I offered a trade with Japan, they said "what is to stop you from doing the same thing to Japan as you did to germany?"

Hypotheses: 1) The AI search for trade routes does not work consistently. 2) Somebody stepped on one of the land or sea route squares.

I suppose that a paranoid AI is interesting, in a way. Like real govermnents.

Hypothesis 2 is the one more likely. An example:

Let´s say that you are playing on Marla´s World Map, are in Europe and have just reached the medielval age. You have a sea trade route with China that goes around Africa. You only have triremes and do not own the Lighthouse. Now, at the west coast of northern Africa there are some parts where the passage of coastal tiles is only one tile broad. This is where your trade route goes. If some civ that you are at war with move a ship to one of those tiles your trade route will be cut of. Normally it would simply pass by the ship on the closest tile, but since those tiles are in this case sea or ocean this is not possible. The same thing happens if an enemy of yours build a city at the coast and your trade route falls within it´s cultural borders.
