I think that the main issue is the false sense of urgency to begin with. Because if you take a couple of long rests before you get to the Grove, you’ll get comments from your companions about how the transformation isn’t proceeding like it normally does. And that’s when you start to get the sense that maybe something is different with you. But that relies on you taking two or (better) three long rests before the Grove. You have to long rest pretty frequently to see the content that makes the game makes sense. But the false sense of urgency discourages long rests. If I were you, I would just start the game again and take long rests more frequently. That should help make the story make sense.
