There really shouldn’t be any confusion. The fact that you feel the need to come here and explain how to do it shows you fail at game design. You see, things are supposed to be fun to do and not a confusing broken mess of wrecked up garbage.
I’ve honestly had jobs that were less of a broken mess of complicated crap than these unlock things - not just mechagnomes either. You had a perfectly good system where players buying an expansion got new races but nooooo, you wanted MORE MONEY so you put in rep grinds and half-assed unconnected achievements and chores and work and meta-bollocks and now look.
Bugs. Lots of bugs. On top of chores. Fantastic.
