tomatovv, replied in another thread: they will fix it in the patches, it's a bug.
Not sure, but it seems the army doesn't increase.

So, yesterday I continued playing! As Winner advised, I didn't go to save Gwendolyn, because my army was still too small! And I went back to the surface. Yes, I agree, the red one is a bit annoying with his jumping from a one-way teleport. It makes it difficult to travel long distances. That's the hellish hero Malik)))
I encountered serious resistance in the level 2 Castle (the maximum level 2 Castle), which is located under the Duchy of the Deer! 150 Broodmothers, 380 Lilim, 177 Devastators, 24 or 34 Lords, and others by default. My army: 74 Golden Guards, 70 Knights, 155 Guards, 158-160 Archers - 200 Vestals, and 74 Ultimate Griffons.
I'll say this: we won the battle with five spells: Summon Elements of Light, Healing, Mass Healing, Mass Resurrection, and Blindness. At one point in the battle, I had only one Golden Guard left!!!! I already thought that was it - I had lost my main striking force... BUT! I managed to cast Mass Resurrection! and positioned the Elements of Light so that they not only killed the Sadists with their counterattack, but also resurrected 20 Golden Guards!! Then, Blindness on the Broodmothers and focus on Healing and Resurrection!!!!!!!!!!!! There were no Seraphs! They are in the Castle! As a result, yes, I skipped three turns, and Blindness lasted for five))) but I healed and resurrected the ENTIRE army!!! Mana?? Plenty! Meditation + El-Sara's Robe (-50% spell cost)! So, I got as much as 87,530 experience!!!))) and the hero became level 30))).
Svetlana appeared - she destroyed the Castle. And stopped. As I understand it, that's how it should be))
The map is interesting! And beautiful, especially the village meadows.
I'm playing on!
