I just got Lilith into my nest, I unlocked the tower and I realized that I was missing just one S.shrine to make the full shrine. However I can't seem to find it, I've cleared every village and the castle, there's no chests left and it doesn't appear in the shop. I have the same problem with the ride 1, I only have one piece and the rest is nowhere to be found. Is it a bug or is the missing piece further in the tower ?
