Before everything: My personal tip for you is to use WSE2(there are some small errors in this mod from it but it works perfectly fine) - it increases your performance drastically and in theory you may even be able to do 250v250 battles.
To fix invisible cursor, delete cursor.dds from mod's textures folder.
This mod is a machine translated(main parts are being manually re-translated though) version of Russian Civil War submod, which was available only in Russian language It adds real world map, different troops, factions and such.
Features
Translated troops, parties, locations, items etc by machine and then corrected many errors.

Added tweaks:
-Cattle follows player

-Increased battle map sizes
-Decreased lord escape chance from 70% to 25%
Fixed snow texture(replaced it with the one from L'aigle)
