Have made a very cautious start on this project.
my revised sett mech / EDB seems to be doing a good job of restricting income - at least for scotland anyway - only another 24 (?) factions to test
should work better for 2TPY. Have yet to get that working as I'm reluctant to start messing with the campaign script until certain issues are sorted out.
testing today - found that the wooden forts on campaign map turn into stone forts on battle maps.
(but they are temporary and the ai does like sitting in them rather than defending cities or if it has lost a region.)
had a look at character traits - I am tempted to remove the slave faction merchant can't move trait/triggers completely.
