Thanks for clarification.
The challenges are supposed to be a noob guide, I agree with that. But now imaging a real noob starts a new game:
"Harvest honey from tree stumps with a stone axe". Noob harvests honey from a tree stump with a stone axe but challenge still says 0/5. What does noob do? Right, he doesn't understand, thinks either game is bugged or he is too stupid to understand.
"Harvest some short iron pipes with a stone axe". Noob harvests iron pipes from different materials but challenge still says 0/10. What does noob do? He thinks he has not enough brain to play this game.
"Harvest some scrap polymer with a stone axe". Noob harvests over 100 scrap polymer with a stone axe, even builds his dew collector with that polymer. Challenge still says 20/100, though. What does noob do? Correct, he eventually starts to cry and questions his whole existence.
"Harvest some rotting flesh with a bone knife". Noob kills 10 zombie dogs and harvests their rotten flesh with a bone knife. Noob looks at this challenge and it still says 0 rotten flesh harvested. What does noob do? You got it, he goes to university to study 7D2D but even with a diploma he won't understand how those challenges work.
Those challenge descriptions even say "you can harvest rotten flesh / leather / pipes / polymer from stuff like bla bla bla but most of the bla bla bla they mention don't actually work. It is just horrific game design and should have never been implemented like that. If this makes it into 1.0 stable I'm running out of words.
