They all went NUTS and attacked each other!
What I TRIED to do was insert some NPC's into the Tavern/Inn you start out in, in Undermountain, and just to 'populate' the rooms, and I tested it out in single player, and they all went crazy and killed everyone (Me too)!
I even made sure they were all True Neutral. I guess I gotta edit their other stats or something to make then non-hostile.
Freaked me out.. Imagine going into a REAL Pub and everyone stops and looks at you at the whole room breaks out in a fight!! --wait a minute... that HAS happpened in a Pub before. Minus the FIREBALLS though.
