Also, because of this, you can create a pretty good stack of ghouls.
However, in my case, it coincided with the fact that I didn't like my priest's upgrade path, so I quickly replayed the first mission, which is easy. After replaying, the intelligence data already reflected the Necropolis's actual strength.
Try replaying the end of the first mission and then proceeding to the second mission again.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
