Wasn't the AI supposed to follow the same rules as the player?
No, they are playing a different game than the player. It is just not overly advertised, and thus people say they are cheating because of it. The point is that the rules the AI follows are different and should be equivalent to the player. The random events are designed for the player not the AI. Also, turn quests are usually non-repeatable, that may be a symptom of the problem as well. But since Heavenfall says they wouldn't trigger I'm confident that they will not trigger for the AI in general.
