Thanks a lot. the FUCK utility seems not to have any possibility to edit the number of levels NPC gain. Any clues? I wanted to investigate the level6 bug - that doesn't allow NPCs that have 6 levels to reach 6th (Namely Vic, sulik, goris and dogmeat), it's kinda irritating, but since I don't know which variables are connected with the level-uping..
Or maybe it is a hardcoded bug?
I've heard that the only way to bring them to 6th level is adding a dummy level 7, so this 'bug' will treat lvl7 as the last one and allow your NPCs to reach 6th. I haven't tried, maybe it's just a rumor, but since the MiriaMod creator did that in his mod..
