Thanks to everyone for all the help! I've been able to do it, incredibly! Still testing, and some things won't show up until later, but I do have one problem. My stone wall is not showing up on the campaign map. It's on the battle map, but not the campaign-looks like a settlement before you build a wooden pallisade. Anyone know what controls that?

And RM, that file that Dimebag has posted should help you out, I think.
