Some more info about Problem Child achievement.
I've tried also by completing chief of mischief aspiration on young adult - no use.
Then I've tried by making the same mischief kid from above declaring an enemy on both his mother and father. Again, no achievement. Only angry and very angry emotion. Bah.
I don't have any more ideas what could devs set as a problem child in this game. A kid that skips doing homework perhaps? That would be cretinous.
So I'm abandoning that achievement until someone gets it (if it's even possible) and posts the correct requirement.

Erm... I'll make a fresh thread about collections as elements are tied to minerals and can't be collected separately.
