I've read that once your herb garden is level 2, you're supposed to be able to ask one of the NPCs to plant specific herbs rather than random ones. I've also heard that this is contingent on having Fiona (or presumably some other follower with the herb trait, if you have one) assigned to the garden.
I do have Fiona assigned to my level 2 garden, but not only can I not request anything from any of the NPCs there, Fiona herself does not appear anywhere near the vicinity of the garden, but is still hanging out in my main garrison area and giving no dialogue options other than the standard "I need you to come on patrol with me" when I click on her. I've tried removing her and reassigning her to the garden, but it doesn't help.
Anyone else having this issue? Am I doing something wrong here, or should I put in a ticket about it?
