I doubt the Juhani mods are the cause of this, as they're simple reskins/remodelling of her face and default clothing. At any rate, I've recruited and talked to her, but haven't yet started her sidequest.
You might be on to something with the Sunry mod, since it should trigger in the area I'm trying to get to. In all of the saves I've noticed the problem with, I've triggered the quest by running into Jolee's friend on a non-Manaan planet. In the save where I first noticed the glitch, his wife talked to me to trigger the quest properly, and I'd talked to the judges about it.
I'll try deleting the mod, and see if that solves the problem.
Thanks again for the help.
