The bad thing that it's not really an option to equip companions with grenades anymore. I used to allocate the extra weapon points to grenades on my companions so they became quite effective with them. It's also kinda strange that every town in the game sells grenades but you are the only one who can use them. (and your companions if you are crazy enough to equip them for every fight)
We could have a larger pool of grenades in the player inventory, from where the companions would re-equip themselves after fights. Or you could tell them to buy grenades and it would be added to the weekly wages.
After conquering Warsaw in the Polish storyline, the king took my city for himself (Koeningsberg). Didn't even say or demand anything and Warsaw also went to someone else. Even though the city is not mine anymore, if someone is found not paying taxes etc, that money still comes to me.
I would suggest giving less illnesses to the troops. Every few days is too often for a party of 30.
Maybe make a counter that resets every time you visit a town or make a camp, and long times without a rest have a small chance of creating an illness.
I agree about the disposable grenades being useless. It's too much hassle buying and re-equipping them between each battle. The low ammo count of the grenades in earlier version was balancing enough. It would be nice to have some some grenade troops also in the game.
