The most absolutely cursed thing about this whole debacle is that the competition's delegates emailed us (the staff) ahead of time to be extra careful with scrambling and make sure this doesn't happen, and then it still happened. Sigh.
(All the scrambles I signed off on are definitely correct (not counting 6/7/mega, where I still got the majority of scrambles correct regardless), except possibly for accidental moves made during transport which wouldn't have been within my control anyway.)
