It doesn't look like you'll be working on this mod at any time soon, but just in case someone else wants to work on it, I have a few more bugs to report:
* If you encounter a battle between a general's forces and some raiders, and choose to enter the battle on the side of the general, your reputation with the Outlaw faction goes down, which has the effect of having them attack you no matter how large your force is and how small theirs is. I've had a flying column of 150 heavy Swedish knights get mugged by 3 brigands, for example. Conversely, if you encounter a battle between a general and some raiders, and choose to support the raiders, your reputation with the Outlaw faction goes above zero, which causes you to be unable to attack them. You get the "I'll give you nothing but a boot in the arse/I'll pay you not to bugger me" dialogue, but you can't initiate combat, all you get is a dialogue saying "leave."
* Generals don't seem to mind if you slaughter their army and take them hostage as long as you do it in the middle of a battle they're having with someone else. If you subsequently release them without ransom, you end up in the silly situation that having attacked them and murdered all their comrades makes you their best friend, and you get a huge bonus to the relationship with their nation.
* You can't build banks. Ever. You can get the dialogue that the city has not yet built a banking house, but the option to build one never appears.
* As others have noted, a lot of villages have ridiculously high hills in which houses are embedded, and ridiculously low valleys in which houses are floating.
* Instead of convincing generals to join me, I usually support a rebel leader and simply capture all the faction's generals and imprison them until I've won the revolution, so that I get to personally own all the castles. This has the result of having the new king (or queen) thank me for my help, tell me that I will always be the war leader, then immediately choose someone else to be war leader. I'm never even considered for the position, which seems to be either a bug or a scathing commentary on politics.
* The AI might not need to feed their troops, but I do. I am frequently ordered to accompany the war leader on a campaign, dragged across the entire continent, and then forced to cool my heels for a week of siege... with two days worth of food. Leaving to get more supplies makes me fail the quest.
* On a similar note, I am often tasked with getting X heads of cattle for the war chief... who then gallops off across the continent so that it's impossible to get the cattle to him in time. Perhaps the option should be available to bring beef instead of live cattle?
* "Even though you have the engineering skills of Leonardo Da Vinci and could blow down the wall of that castle in your sleep, I, your war chief, order you to build ladders and feed all your very expensive, carefully-tended cavalry into a meat grinder at the top of some rickety ladders, at all costs!"
* Some of the unit names need to be made more explanatory, and they should all have unique names. Trying to decide whether I should turn my Curaissers into... Curaissers when promoting them seems odd. It also seems strange that Tatar raiders lose their horses when they advance.
