In my singleplayer campaign, I mistakenly entered into this endless mercenary contract, and soon noticed that in every battle the lords of my faction (Southern Empire) are only using recruits and other low-level nonsense, while the enemy has access to cavalry, elite infantry and so on. I did a little research and found that in the entire territory of the Southern Empire there is not a single option to hire anyone except for recruits, not even those recruits that subsequently improve into cavalry, when all the neighboring nations, on the contrary, have the opportunity to hire advanced soldiers even in the poorest villages. What is funny, when the enemy captures a village belonging to the Southern Empire, there's suddenly appears the option to hire advanced soldiers, if we take the village back, it disappears. Naturally, when there is not even a single experienced soldier in any of our armies, we were quickly swept off the map, and I can’t leave the faction, because the mercenary contracts in this game are endless. I had to delete the save.
