Logan killed the archdemon in the background (Dragon Age: Inquisition)

In the Inquisition of the keep didn't load the world, and no error was shown, as if all have loaded successfully. But the game itself is not with my decisions, and canonical.
Through trial and error, it became clear that not loading the background if Logan died killing the archdemon, and the dark ritual was not performed.
But if the guardian dies killing the archdemon (no romance with Morrigan), the background is loaded. Also when the ritual prehistory loaded.
In connection with this question: has anyone tried to play with the backstory, where Logan kills the archdemon? Well, or maybe someone knows what about this is officially stated?
Again, no warnings or errors anywhere did not get out

As it turned out, the bug is not in the transfer history, and in the second volume of the Code: a Study of the Fifth Mora, where my solution Logeyna still is written about the penalty
