Looks good with the new ground texture! Which file are you modding for the ground texture?
Interesting that the first screenshot has all buildings present but all the later ones have missing buildings. Are they all in the same GUI or was the first captured in the old GUI?
I notice quite a few buildings have gone missing as well as the roof of the house in the south west corner. I wonder if that is because we have reached some limit on the number of objects which can be rendered by the HistWar engine in the 3d view?
can you post an aerial view which shows all the town? Just to see how many have disappeared.
Is the Village and hamlet ok with your new ground texture, or are there missing bits for those too?
The first screenshot has a nice brightness and contrast for the buildings but the remaining ones look rather too grey compared to the environment: why might that be? I have found that sometimes the bump map can make my buildings too dark. You might try replacing the bump maps 0000B.dds etc with these which I made with an improved technique:
