Thanks for the heads-up! It's possible there's a bug lurking in my code, but the server doesn't appear to have a solution from you for the "Reverse Sequence" puzzle.
Any chance you could double-check and see if you have a solution for that one? If so, could you run it again in the game and see if that updates your count to 30? If it doesn't, could you email your solution to sic1@schemescape.com so I can take a peek?
Side note: even if your solution hit an error in my code on the server, it should have been tracked, so this could be unexpected. A network error is one possibility.
