Yes, just code, for have more things to does when I am lord or king in administration, I finished all constructions very fast, and in the end, my income is much low than a lord AI.
I have played Silverstag some years ago, the administration is very good, but is not a balanced gameplay in battle, and I stopped.
Look at they list of constructions, http://silverstag.wikia.com/wiki/List_of_Center_Improvements
A lot do not need, is very repetitive and much work to do. But my sugestion is something like
They plantation system and fire system, where you can get more profit after months with plantation, and the fire, where you lose some of constructions after loose a battle in village, castle or city. Something about 20% to 30% you have in that, and you need to create that for reduce that porcentage to half.
My best ideia is make the enterprises from city, in a village, with a construction in list like another buildings, but without limite of one type like in cities, and with constant money from that, or based in village prosperty, but generate low money than a city and if same price to build, something like 50% than generate in city. But if you will make that, please make the fire building before, and the system that you loose some building if someone plunder your village
Better than it, when you build a construction in village, you need raw materials for that work, build construction like woodcuter in village, that generate wood for industries in this, but you need to pay money weekly, so they work.
Things like blacksmith is normal just have in city, but bakery, have in village too, just use logic.
Raw materials for build construction than just money is good too, every building need money for pay works, but you need to give raw materials for that too.
Others ideias from me, is create a spy guild, for when you use the spy action from diplomacy, you need to have that building in city.
Or guards outpost for village, for when someone attack village, this generate 10 medium soldiers of your nations, than just peasants to defend.
Have anothers mods, where you can recruit elite troops in a city, can you make that action enabled from construction? more expensive than hire and upgrade that troop, but is a good way to get a elite troop fast if you want to pay more.
Sorry for ask for much things. But is that I like to play, a lot of mods put parts of this, but never create a game with quality and balanced gameplay, anothers make, but with much texture in folder, not filtring and optimizing the game, and anothers create with scripts error, and in game they have a lot of bugs and crashes.
I looked your work, you put much texture but with good organization in folders, for do not need to read what you not using, that make the game run much faster, and you work with graphics, sounds and life in city, make the game much more good to play, more pleasant.
