Yes the castles change, but it would be nice to have the towns and villages change. Especially when you select a small faction culture and you use them far away. EXAMPLE is I use Navarre in the balkans, I would not have to hike all the way back. Or seND expensive recruiters. Also lords never fully use your set culture troops they also get reinforcements from villages it seems. After a while my lords have 3 to 4 different troops.
Not a huge deal though still my favorite mod. Thanks for trying buddy. I also had the problem where I could not recruit any troops at all. But if your a noble under a king it works. But you can only recruit the peasants troops from the villages and tows which is weird that the militias disappear.
