On the mission in Skyrim called "A Return to Your Roots" where you are supposed to deliver the Crimson Nirnroots to the girl and she tells you about them? Well I already collected all 30 of the Nirnroots but for some odd reason when I go talk to her the message that says, "Have you ever heard of the Crimson Nirnroots?" WILL NOT come up on the screen!

I've done everything I could.

The mission is active. I've made sure to select every option. I've slept in beds. I've waited hours. And I've even punched her! What am I supposed to do?
