Quern unlocked by carpentry?

[Feuer]

Now I'm no expert, but I know for a fact querns are made from stone, not wood.
And I could be wrong, but the quern build function is unlocked by carpentry, or farming.

Nothing major, but none the less annoying for people like me.

You wouldn't need a quern if you don't have wheat or tobacco (and according to wiki you just need stone working so idk...)

pretty sure it's unlocked by farming since it's used only to process things from your farm
