Interesting, but got stuck #6

Hi, a very nice solver.

Interesting because it applies those strategies. Visually appealing because it displays them and also shows what's going on in the grid.

But unfortunately it got stuck on a specific puzzle file I tested. I had tried that on paper and wanted to see a possible result by running it through your application. It got stuck after maybe 20 steps, reporting 'unsolved'. I don't know if it is a particularly hard puzzle.

I noticed there are a number of unsolved puzzles in one of your directories too.

So I wondered what the status is. Might there be some bugs, or is it a matter of working out more of those strategies?

I am particularly interested because I might work out my own version of this.

Can you post the puzzle? I've forked the repo and implemented a couple of other strategies. I would like to see if they could solve it.
