Yeah, you can't sweat over a single answer choice. If you left the test center feeling good, that's excellent. Keep yourself busy until greyday and don't even think about it.
And as for lost tests @jonathan.hatcher7 all I can find is where they lost more than 280 exams from 3 test sites in 1999, over 50 from the University of Tampa in Florida in 2012, and around 80 from UC Santa Barbara in December2015

Per "TheAdmissionsSherpa", they have a "source" which said that the greyday is happening today. Not sure who this source is though...hmm.
I am afraid to refresh the button might go out LOL
