Hero Video

Perhaps my topic is just a panic-driven misunderstanding....BUT!
From mission to mission, I am becoming more and more convinced that not all video clips between missions (and during missions) are shown.
The first sign appeared during the Necromancer Campaign; the treacherous Markel was supposed to perform the "Ritual of the Night," but as far as I can tell, he didn't... Whether this is true or not, I don't know, because after defeating Gordic, there was nothing but Markel's desire to kill him. After that, for some unclear reason, Railag appears and begins to conquer the clans...BUT HOW DOES THIS RELATE TO Isabel and the Griffin Empire...I have no idea.
Glitches in Heroes started happening after they were upgraded to version 1.50.
After completing a mission, a rating table appears (which wasn't there before), and after another click, the next mission appears immediately.
Dear players, is there any way to download this video somewhere?
