Whole cities - I don't think so. But there are battlefield generation scripts based on climate and ground type, so if somebody would take a look at them - I'm not THAT good of a modder, these codes make my wee head hurt :) - he could probably get to appear more farms or houses etc. on the battlefield where these objects are.

BTW, the other tip means the walls are now burnable :) So if you don't want that, leave the 'stone_inflammable' entries unchanged :)
