Just some old drawings quest question

[Killer29687]

So… am I missing something? On ch 5 if that helps, have the quest first phase done aka I researched the drawings but it points to her lab and I’m finding nothing… is it tied to a specific mythic path? Currently on angel trickster azata (zero issues thus far) my only guess is it must be either ch 6 or it’s for demon path… in which case very odd cause I did not touch anything involving that meaning this is vanilla bug
