Sorry about that. Due to a slip-up by me, there is no common 9-letter word in today's Challenge - but there are two rare ones.
I don't want to go into it in detail until the puzzle is closed, but if you search for either of the 9-letter words in the forum, you will find a discussion from the last time these nine letters came up. It was suggested that the wrong word was common, but I concluded neither of them should be common. I changed the common one to rare, but forgot to remove it as a seed word for puzzles. Oops!
So, if you have the scoreboard set to count only common words, you won't get any stars, even if you find the two niners. But, then again, nobody else will have any stars either.
