Not official… the crafting spec was always one of its kind it was/is missable because under certain circumstances the NCPD scanner hustle boss won’t drop it… it depends in which stance you kill him in close or range : /
if you done the ncpd scanner and he didn’t dropped it you are most probably screwed on this playthrough : /
if you are playing on pc you might spawn it via console comments on consoles there is no way to get otherwise
