Carbonite\NxMap.lua:3789: attempt to index field
 

Getting this in BugSack when entering Brawler's Guild:
2x Carbonite\NxMap.lua:3789: attempt to index field '?' (a nil value)
Carbonite\NxMap.lua:3789: in function <Carbonite\NxMap.lua:3680>

And getting spammed with this in my chat log:
Carbonite GetPos Err:925: Carbonite\NxMap.lua:9150 in function 'GetWorldPos'
Carbonite\NxMap:5258: in function '?'
Carbonite\NxMap:4797: in function 'Update'
Carbonite\NxMap:3759: in function <Carbonite\NxMap.lua:3680>

I can confirm that I am receiving this same error. It is spammed to chat and requires a /reload after exiting the arena.
