The Necromancer path map crashes; the game is unplayable.

I completed it with a hero in 145 days (I got a Cyclops). It was difficult at the beginning; I was leveling up Zoltan because Arantir suffered heavy losses without the "Raise Dead" spell (by the way, they could have given it to him, plus the "Lord of Life" ability). After about two or three weeks, Zoltan reached level 20 and, in general, successfully repelled the attacks of Giovanni and Benedict without any major problems. Then, with Zoltan (level 29), I locked up Giovanni, and Arantir went north, where he successfully developed to level 31. Of the enemies, the most formidable turned out to be the last one – Benedict (a level 40 build with a lot of creatures), but he made a mistake by chasing Arantir and catching up with him in the upper-left castle. Naturally, I destroyed his catapult and stunned the archers, and as a result, he just stood near the walls, obediently taking my spells like "Charm" and "Berserk." In general, the battle ended without losses (I had about 600 vampires and about 300 liches). Overall, I liked the map, but I have some questions (perhaps rhetorical). Why make the hero's path to the Barbarian castle so complicated (what's the point?). What to do with new artifacts like the Skull of Corruption and the Bundle of Wood. Finally, I still don't understand how to capture Giovanni's castle (the game ended, but he, the scoundrel, remained alive). But still, thank you to the author for the work.
