Grave keeper is just saying "..." Instead of opening Jiangshi lanterns for me. I already have one Jiangshi in the graveyard, but it's not letting me talk to the grave keeper to open the lanterns for the ones I caught afterwards.
Are you sure you have a "Soul Lantern (Jiangshi)" item in your inventory? The dialog to release them only appears when you have a captured Jiangshi in your inventory.
