Trade diplomatic bonus mod

[Cavendish]

Hi all,

I would like to make a mod in order to give the diplomatic trade route bonus (+20) not only to the importer, but also to the exporter. Something like trading raising mutual relations between the partners. But I dont have a clue on how to do it.

Suggestions?

I think start in the cost and defines files. Maybe it is a set value somewhere. Hope this helps
