skill tree seems to be working fine for me as the editor. I too have had few times where I add weapons that they show in the save but not the game for some reason. I havbe noticed if you choose not to have a craft plan (none) they are less likely to show in game. just the way it is for me. I was wondering is it possible to edit the ammo for a gun. I was playing with another person who had an unlimted ammo shotgun and it was crazy... He gave me one I would like to have it for me rifle.
