But if you are playing a 6 player game, that is simply not possible, since there are only 4 neutral tokens of each NPC character. What are you supposed to do in a 6 player game, balance it choosing more NPC than usual? Or focus on befriending PCs?
I don't know what is wrong with your copy, but the copy I played neutral tokens are double sided witha different friend on the otherside.
You shoudl easily be able to get 6 tokens of 4 different neutrals.
