Great mod!
Most errors I have noticed have already been mentioned.
-One thing I have noticed is that the Black Land Mercenaries hold their shield sideways (45 degrees)when defending. Seems illogical, was this intensional?
-Population growth seems out of control. (I have never liked grain resources.) Most of these town were here and of similar size during the War of the Ring, why would they now all shoot up in population and become large cities?
-The path between Mordor and the town north of Minas Morgul is too narrow and the game doesn't put in roads.
