In the solver, trying to edit candidates leads to an x/y NaN, which makes the solver unuseable. Chrome 126.0

Just found your solver. I absolutely appreciate the step-by-step solving so I can actually learn how to get better instead of simply looking op a solution. So just thanks!

Fantastic and thanks for the feedback!

Is it my finger trouble, or have you stopped supplying strong link data on simple colouring checks?

Andrew Stuart writes:

Fixed now, refresh. Yes something I was fixing yesterday caused me to delete something I shouldn't have. There's a reason I don't work on nuclear reactor code ;)

I was working on your December 2023 Puzzle Pack No. 19, got stuck, so put what I had into your Solver. The Solver proceeded normally then it got stuck (read "wait") and stayed that way. Is this one unsolvable? BTW, I enjoy your puzzles and Solver very much.

Thanks.

Just give it a moment and refresh. I'm trying to track down the source of crashes. I get an alert but very little information. I think it is to do with simultaneous users or just being too busy in that moment. But it self-recovers.
