I also had some problems with this stage of the campaign. After reading all the pages of the forum thread, I decided to replay it from the first mission. On the second try, I managed to develop Anthony normally; I still don't understand what the catch was; I was already playing with the latest patch. But yesterday, I completed the map in 5 hours without any major problems, and the closer I got to the end of the game on the map, the fewer problems I had, even with neutral creatures (when trying to obtain the artifact). In the first week, I captured George's Castle, and then, without waiting for reinforcements, I headed to the Dungeon. There was a fort and a hero; I could only defeat the hero on the second try, but after that, there were practically no problems. - Castle across the river, then the castle at the bottom of the map (the first Baron). Then the castle higher up, with the golden glows. Maximus and Cordelia often visited. Somewhere at the beginning of the game, I got an artifact that prevented retreating from the battlefield, so the opponent couldn't inflict damage on my army with minimal losses and retreat. From a certain point on, there were no problems at all; their armies were destroyed with minimal losses. The teleport from castle to castle and the altar of resurrection were very helpful. I finished in about 7-8 months; some slots in the army had 1,500 units... monks, crossbowmen, guards, about 500-600 griffins, 700 cavalry. I can attach a screenshot of the army and the hero's stats. Kirill was defeated without any problems. After Kirill, there was a hero in the Dungeon, in the Undead Castle, who also didn't pose a threat. He gave me a bit of a hard time, but that was the last battle... ... Yes, I was playing on "Normal" difficulty.
