Lustrous Orb is not where it should be.

[Caiomenezes]

Hello,
I'm having trouble obtaining the Lustrous Orb in order to get Palkia's seen data. I'm already the Sinnoh Champion, and I've followed all the known steps:
Spoke to Professor Rowan and Dawn;
Interacted with the TV in my in-game house;
Fully explored all known locations where the Lustrous Orb may appear (especially Wayward Cave);
Repeated these steps multiple times, including redoing the Sinnoh Elite Four.
I already have:
The seen data of Dialga (from a long time ago);
The Dread Plate, recently obtained at Old Chateau;
The seen data of the lake trio (also recently obtained).
After each new step, I repeated the process: talking to Rowan, Dawn, checking the TV, and fully exploring Wayward Cave again — but I still can't obtain the Lustrous Orb.
Could you please help me identify what might be missing or if there's a bug affecting my progress?
Thank you in advance!

Good day @Caiomenezes

 

I apologize for the inconvenience. There is currently an issue known impacting the Lake Trio Quest. 

 

This issue is being actively investigated and I will be in touch when it has been resolved.

 

Thank you for your patience.
