In the third mission of the In the Wake of Gods campaign, is there no structure on the right to revive Alesha? What could be the problem?

Ksorich is in the Dungeon; you can get there through a portal – where there are a lot of skeletons (the path is to the north; thieves are standing there – to the left of the city). First, you need to defeat all the enemies in your path and reach the hero. After defeating him, you will receive rib armor, which you can use to pass through the portal.

I solved the problem at the beginning of the third mission by re-saving the save file from the beginning in another version of WOG-era, as I was playing in the Legend of the Red Dragon mod. After passing this difficult section, I transferred the file back to the game with the mod. However, the graphics for some structures became a bit distorted, but the main thing is that they didn't disappear. Also, in this mod, they overdid it with the level 8 creatures – capturing them is almost impossible. Instead of the 1-10 units indicated in the overview, there are actually 10 with 250 each, and each has at least 1000 health. In general, it is almost impossible to defeat such an army. In a classic game, capturing these creatures was not so difficult and gave a noticeable bonus in subsequent battles.
