I feel ya. Neither of my paths got updated, so this update had nothing for me. I was on the suspicious of Laura path without Aya. Other save was the suspicious of Laura path with Aya.
Ended up having to do a whole new game just to see the new content. Still keeping my saves though for when my main paths get updated.
On a side note, guessing this is the end? So now it's just different endings coming and the full implement of the Aya stuff? So don't expect anymore new scenes or continuation of the story I'm guessing, since it is just endings now that will be worded differently depending on paths. And yeah, agreed about that last scene as well. That was a rather abrupt jump for such a long anticipated moment. Maybe it will get more added to it later when the rest of the endings get finished (hopefully).
