Thanks Eldjötnar, that quest is the only remaining. I have no other. I've tried every interaction possible in the house with Lyriel and it still does not trigger. Any other ideas?
Could you drop your save here for me to have a look?
Your save(s) will be located in AHITR/Game/Saves. They look something like 1-1-LT1.
You can use any file sharing site (Google Drive, MEGA, etc) and paste the link in a reply here. (Just make sure the link isn't set to private when sharing!).
Alternatively if you wanted you could DM me on Discord and I'll have a look there!
