Battles with neutral creatures.

I want to share another problem that sometimes occurs in single-player (it cannot happen in Multiplayer by definition). There are scenarios where the victory condition is to destroy a specific hero. When playing on Champion difficulty, I have repeatedly encountered a situation where this hero dies in a battle with neutral creatures (only his tomb remains). And even after completely destroying all enemies, it is impossible to finish the game (the standard victory conditions do not apply). Sometimes this is only discovered at the end of the game (and the death could have happened at the very beginning). How to resolve such a situation? If the AI clears the path to the tomb with its last city, will it pick it up to revive the hero, or will it follow a different algorithm, ignoring fallen heroes? On a large map, there is not much desire to retrace a path that has already been successfully completed several times. By the way, I might be wrong, but I remember that on a lower difficulty level, the opposite situation occurred – on the same map, victory was awarded simply if a specific hero died (either to neutral creatures or allies). I tested the option of clearing the path to the tomb – it works. The only thing left is to wait for the hero to be revived.
