I am working at this time.....will be traveling to Northrend and Outlands later today, but Pandaria is working like a champ.
It is unfortunate to find out that NPCScan is now defunct.
That being said; Saiket did make the NPC series of addons open source.
So hopefully someone with a better programming knowledge than I will come along and continue the projects.
More information on the open source verification and source code
here.
Now Rythal, you have your hands full (period), so unless you wanted to integrate and manage another module to adapt NPCscan and NPCscan.overlay directly into Caebonite, I would skip it and let another programmer come along and pick NPCscan up and run.
???? Where can I find Information/verification that NPCscan and NPCscan.overlay has been shelved ????
I would post something to the various WoW forums for another "anyone" to pickup the program and continue it.
UPDATE
Just verified from the link above of the abandoned projects.
Clearly stated on his Google code page
I will get to work and se about finding other programmer(s) to take in and continue the project
