Describe the bug
I keep hearing the "Fatility" noise from BugSack/Grabber and when I looked this is the error message.

This was in Korthia because today the Nadjia quest A More Civilized Way is up.
It was spamming this message before I even got close to her let alone clicked on the weapon rack.

Thinking about it I meant to report this a week or two ago when it happened on an alt doing the quest in Bastion, but I was racing to get it done before reset and just disabled it. It was about the time you added the addon and removed it from Better World Quests.

I just disabled everything except this addon and it's still doing it.
