Error entering Darkmoon Faire NxMap.lua line 6493

[Tequima]

Hi, had a quick scan but couldn't see another report for this - apologies if already raised!
I get this on going through the DMF portal. Running
Carbonite, v6.0.1
CarboniteNotes, v6.0.1
CarboniteQuests, v6.0.1

and I have deleted the carbonite.lua from npcscan overlay that was causing issues elsewhere.
Cheers - and thanks for all the time and effort you put into this incredibly useful add-on!
