Mission possibly bugged?

[Isola]

If all Wings of the Goddess missions are complete

Head to one of the Cavernous Maw in Batallia Downs, Rolanberry Fields or Sauromugue Champaign for a cutscene.

Did you do that?

Also, did you do "A forbidden reunion" you must do this one if you have not, at your level of progress.

and

If you are stuck without a Lightsworm, go to the Goblin Footprint in Batallia Downs (S) at F-9 and watch all of the Ganged Up On cutscenes , and then wait a game day. After that check the shimmering ??? next to any of the present day maws in Rolanberry Fields, Sauromugue Champaign, or Batallia Downs to get the option to raise your Lightsworm.

You will receive the message "The bonds tying you to Altana have strengthened, enabling you to experience all the memories of Wings of the Goddess!"
