Good day
There is a group of lunatics residing between SGS and the GMS compound, they live behind a partly fenced off area of the map. There are three lunatics on normal, and five on hard mode.
As they are deadly for low level characters, I used traps and the noise from a grenade to lure them out without getting into combat. Normally such NPCs come to investigate the noise, and then return to what ever they did.
The new NPCs here behave differently, they just stay where they end up, instead of returning to their base.
It looks like the newly added NPCs are not assigned to have a "home" or "default" position, like the others.
