Don't know if this is intentional change or not but old lore says the Yasuki split from the cairn in the 4th century and new book says 3rd.

I also noticed the use of Utaku over Otaku, but last I heard the current meta was before the change.

The change was a canon way to fixes a translation error. So since they are starting over they can just fixes it from the start with a red-con.
