Searching Civics Granting +1 Metallurgist Jobs
Just like the title above says. I had a couple playthroughs where Industrial Districs granted 2 Metallurgist Jobs and +1 Artificer Jobs, but I can't seem to find it after I edited my nation.

Anyone know how i got this extra job, or where I can do so again?
