process would work fastest if you have enough resources to actually craft something, and can send save with instructions on where to craft and what to craft, etc.
Saves with me standing right where I need to do it are best, etc.
toggle on unlimited skills before loading saves with lots of skills, then load.
see if this helps
I had 6 points. Used unlimited skills. Unlocked 20+ skills.
Saved the game.
Then, while Unlimited Skills was still on, loaded the game, and the skills are still unlocked.
Are you saying this is different for you?
