My, did I ever have quite the disaster just now.
I was working on my current project, and was starting Morrowind to test it.
I went through the chargen, and as I was almost done with it, I asked Sellus Gravius about his background.
He claimed to be an herbalist, and told me about the local public baths, where he claimed to work!
I left to test this, and every person I spoke with, no matter who, claimed to be an herbalist.
I checked the CS, and surely enough, I had somehow unchecked the restriction limiting that message to only herbalists!
Thankfully, after I figured out what was wrong, it was an easy fix, and I found no other problems.
I was really worried that I had somehow ruined the mod... I was so relieved!
