Custom sites not displaying Thread - Third Age - Total War mod for Medieval II: Total War: Kingdoms

Hi,

I have installed TATW on top of Medieval Total War 2 - Kingdoms, and the campaign itself runs fine with the middle-earth map and all the right factions and units.
However - the custom sites (Minas Tirith, Isengard etc) don't show up in the actual combat maps. If for example I lay siege to Minas Tirith, I just end up on a standard siege map against and normal castle - and the enemy units can walk through the walls!!

I have patched main game with 1.3, and Kingdoms expansion with 1.05.

Anyone know what the issue might be?

Thank you
