I just found out about this mod and tried to install it. The mod works in custom battles but in campaigns the old factions are listed.
I downloaded the february build base and copied that mkbase.pack file in the data folder. I then ran the mod installer part 1 and 2 which created mkmodels1.pack, mkmodels2.pack and mkmodels3.pack. Then ran the game using TW mod manager and checking all 4 pack files. I have no other mods installed.
