I got stuck on this level (Honeycomb/Large/Hard/#12) and I always end up having issues with the part that I circled with red because it either wouldn't add up or there would be a space that's not connected, and I've tried different solutions as well. How I could solve that part or what's wrong with my solution so far? I don't really need a solution for the whole puzzle just for around the circled part.
One of A and B must be an edge to continue the known loop (and the other is space). So F must be edge to have enough edges around the 4.
One of B and C must be an edge to complete the 4, so E must be an edge to continue the loop.
That gives us four known edges around the leftmost 4 (E, two for F, and one of A,B), so D must be a space.
And that means that both G and A must be edges to have enough around the upper 4.
So B is a space, and C is an edge.
That gets us to here:
