I never really test this mod, but correct me if I am wrong.
With this sytem we can't continue a trade route if we are in war with an other country. Then, we can't trade with Indians or Europeans(always automaticly). Moreover, when we want to trade with Europe(always automaticly), we must sell and buy all goods manually.
This mod is too incomplete(for me) to add it in DoaNE.
However, Jeckel has done a good job, his system was really better than the old system.
