Problem getting quest from Uberion (Gothic)

I go through the game calmly, I have not met a single bug, but here it is. After I completed the Almonach quest in chapter 2, I went to the ceremony to summon the sleeper. After the ceremony, Uberion should be taken to the temple, and I should speak with Kor Angar there. As a result, Uberion is just lying on the floor near the temple, the dialogue with Kor Angar is not activated, and I have no story missions.
