The Fall of Shanti

According to the plot, there are Dark Elves on the map, who supposedly only appear during the Time of Bitter Ash War, which was much later than the fall of Shantiri, or am I mistaken? Please correct me, or is everything written incorrectly on the official website?

I liked it very much, but because of a bug, I couldn't see the end. The bug is as follows: I free the sorceress from prison, go to the ritual site, watch the cutscene, after which the hero "Town Portal" teleports back to his place in the circle, and I can't do anything else; instead of the cursor, there is an hourglass, and you can only exit the game using Alt+F4.

I approached the secondary hero to Druid Tas Netilu (if that's how it's spelled); he disappeared again, and the same thing happened – nothing happens next, and nothing can be done; apparently, this is due to him.

But at the end, Laura defeated [him] not with troops, but purely with Sorcery + a couple of spells.

In principle, it would be great if they made something special just with Sareth and a map with AI allies.
