I input 3555 (the code from the in-game site), 3549, and 3572. (the substitutions from the page.)
I have logged into the game to check one more, and I may have been mistaken! I swore it was 3555, but it now displays 3855. I probably simply misremembered, and I don't think it would be a bug that somehow went away, especially if that digit doesn't change. Apologies for the inconvenience, and thanks for replying!
