I decided to move this topic to modding forum. And I finished making all 4 maps
The only thing they lack is advanced scripting for now they have custom unit sizes to be historically accurate and working reinforcements. So like before I would be AMAZED to see some HELP FROM ANY FOG 2 MODDER THAT KNOWS HOW SCRIPTING WORKS.

"The Mongols invaded Europe with three armies. One of the three armies was tasked with distracting Poland, before joining the main Mongol force invading Hungary. The Mongol general in charge, Subutai, did not want the Polish forces to be able to threaten his flank during the primary invasion of Hungary. Thus, the Mongol goal was to use a small detachment to prevent the Poles from assisting Hungary until the Hungarians were defeated. That army, under Baidar, Kadan and Orda Khan, began scouting operations in late 1240."
