Walkthroughs for custom maps.

I don't know, but the hero's stats are also incorrectly displayed for some reason. As far as I remember, my army consisted of 598 Archons, 1 Azure Dragon, ≈ 700 Fanatics, ≈ 1000 Snipers, and ≈ 150 Champions, plus war machines.

Also, in response to the question "Message from Marmot: Why can't I see your army in the lower right corner of the screenshot?"

If the HD+ mod is enabled, and the first battle (attempt) is lost, the hero is displayed in the lower right corner with "bare" stats, as if he had given all his artifacts to the enemy hero, and without an army. If the battle is won on auto-battle, with losses, then the remaining troops are displayed, as after an auto-battle.
If this is the first attempt at the battle, the full stats with artifacts and the full army are displayed.
Therefore, it is better to start long battles from the first attempt (and not press the "replay battle" button), so you can clearly see who was in the army and who needs to be resurrected, or at least remember exactly who was there. So that it doesn't happen that someone important is forgotten to be resurrected after a battle for half an hour or an hour. :)
And using the "Resurrection" spell at the end of the battle to check if everyone has been revived doesn't always objectively show if everyone has been raised, for example, if you are standing on one of the stacks, then it cannot be revived, and the "Resurrection" spell shows that no one else can be resurrected.
