Just a quick note, we did at some point redesign the province income as it turned out that the campaign was too difficult for the southern and middle clans to get by in contrast to the very rich northern clans.
However, this fix/ redesign didn't make it into any release yet. It's a simple adjustment which I can dig out for you guys but I'm not sure that it can be used in a running campaign.

P.S.: Enjoying the story so far.
