Rollbacks didn't help. Only starting the game over worked. I teleported straight to him via cheat for a check and the dialogue appeared. I chose battle and was shocked (screenshot). How he did this is known only to the author, of course. But I'm not going to play this delusional nonsense

By the way, his horse wasn't upgraded before the fight; it has 4000 health. How did he kill 2 of my back-row stacks simultaneously, and even bypass a rock?

And look, author!! The point isn't that he's designed to be a cheater, but that I wouldn't have had the chance to replay this battle if I had come to him much later with a normal army and didn't like the result of the fight again! I would have had to start a new game from scratch because reloading previous saves ruins your script! Do you get what I mean? So, I'll save my time, and you can polish your creation until it's in a playable state.
