I've noticed that there are several chances for one of your family members to become corrupt for staying in a large or a huge city. There's a trigger for them just being in one, for it having a large enough market, or a bank...to the point that within a few turns keeping them there becomes a huge liability. I'd understand the income reduction - as these cities on it's own can make you such large amounts of money that you would never have to worry about it again, but having them become less loyal and useful for keeping order in these cities is just wrong. Is this intentional, and will it be addressed?
