Fun extension, but as an FYI it seems to have some issues with the Savage Worlds ruleset. Particularly I was trying it conjunction with the

I was getting a similar error even without the NPC Maker extension, though, whenever simply creating an NPC and modifying the Damage role. I'm guessing there is something about the way Savage Worlds uses that "pairs" function to parse through attributes that is causing the problem, if that means anything.
