The single moon on the top right. I think the design intent is to recognize it cannot be paired, and then that forces the solution for the section left to it.
However, this violates the rule "each puzzle requires something drawn".
You can argue that the moon itself counts, but chapter 5 violates this even more egregiously, with two empty hexes.

I think Chapter 4 has a mistake.

You're absolutely right. Thanks for pointing that out :)
EDIT: Should be fixed now, thanks again!
Wow, that was a quick turnaround!
As an aesthetic thing, I think it would look better if the moon symbol looked like 'the opposite' of the circle symbol introduced in chapter 2.
Really lovely artstyle
Thanks!
