Ok, I've just finished what seems like everything in this release, but the progress screen still says there's one "object" missing (it says I have 12/13).

I don't see/haven't seen any hint at all of such a thing. Where should I look?

How do I get Clover and Petra scene and Katarina 7th scene

Where's the last memory fragment thats unlocked after completing the Hawk Club final stage? i cant find it
