Not sure anyone ever got it to work as important NPCs would be immortal as long as you were in the map, but lost their protection when you left and returned, or could die when you were in some other map, or the NPC changed maps and lost his immortality in the new map.
Can't be sure, but Technobacon may still be trying to get it to work in Stalkersoup.
Better keep this short as we shouldn't do this here. The Mod Discussion thread for the mod is the proper place.
A preoccupation with the next world is a clear indication of an inability to cope credibly with this one.
So I realize this is a bit of thread-necroing, but I have found this pack to so far be the best version of NS around in terms of content/stability/english translation yet one thing that bugs me is not being able to figure out how to add mods to it, ie which ns mods fit and where to get them. Namely, the biggest problem imho with NS is the mortal NPC's which can seriously screw up some quests.. I remember there were NS mods floating around for quest npc immortality but can anyone link me to something similar for this particular pack? Cheers
