Lol. I dont know what version of Ran No Jidai your playing but it can't be anything offical. But I can't remember the pre hotfix release and if I removed any units from the Descr_Strat.
The obvious remedy is to get rid of all those stacks. Thats why your on -12k. This is a tough mod. Even with two towns you'll struggle to support a stack. Thats because I'm lazy with the resource side of things, preferring to work on titles all day and learning feudal era japanese.
However for the sake of service.
What add ons/sub mods/additional downloads are you running with RNJ.
