This is a great mod with lots of potential, but I have noticed a few things.
Sieges don't really work. I know the AI is terrible and you can't change it but as it is I just can't take an enemy castle.
I think making the walls, ladders and stairs wider would reduce soldiers falling off as much, and maybe extra waypoints underneath the ladders to have them try again if they do. Other than that, I don't really know how one would go about making the sieges work.
The weapon length for a lot of weapons seems to be set too short for the models, causing misses when it should logically hit. If the weapons are meant to be shorter than that is fine, but the models should probably be altered also.
In general the horses are far too sluggish to respond, increasing the manoeuvre would help in my opinion.
Not having any geographical knowledge of Sicily, I find the map to be very confusing and I keep getting lost. Adding some sort of compass so I can keep track of which way is north would probably help a lot.
Although seeing alarm signals from friendly villages is good, there is currently no way to determine if it was just some bandits walking by or a full scale attack on the town. I think historically different forms of smoke signals were used for different messages (small party spotted, village under attack etc.), and knowing more about what is going on would be very useful. More than once my faction lost a castle and I didn't notice until days later.
Battle between parties seem to be over very quickly. For example, I spotted two vassals with about 30 troops each fighting and by the time I got there to join in the battle was already over.
Anyway, this is a really great mod and is brilliant fun to play. Good luck with it in the future.
