Leyawin glitch, Dagail won't acknowledge seer's stone Options

[Duezala]

I've just returned with the seer's stone and spoke with Agata at the Leyawin Guild, who then directed me to give it to Dagail. The trouble is that Dagail won't acknowledge it, even when I'm wearing it on my neck! She keeps lamenting that about her voices. Has anyone else had this problem and what did you do? Is there another way to get my recommendation? If I use a healer spell on the silly cow will she come to her senses?
