A new user, someone whom I introduced the site/community to, posted an answer to this question.
It basically said: "I don't know about the overall problem, but for specific example you give, the constraints will fail after 2 more cells, I checked this manually."
So this isn't an answer, it is a comment. But as a Rep 1 user, he couldn't make a comment, so I guess he posted it as an answer.
Seeing this, I flagged it as "Not an answer". I know moderators can convert answers into comments.
I guess in this case, the moderator thought it was best to delete, or even slipped and pressed the wrong key.
I'm hoping that this can be undone and then converted into a comment.
