However, the biggest problem here, as was the main point, is the ZOI problem. People need to degroup in Cortez and Conorado, otherwise they are easy target for sanctionlancers (Exiles should have a right to escort their suppliers between Bretonia and Taus around the warzone, I believe).
Changing "affiliation" of Kusari Exiles however would solve the most basic problem, because Exiles are allowed to escort traders, but traders themselves are rulewise forbidden from allowing them to do so, as they can't ally with unlawfuls (what also includes escort duties + being in one group).
