Op. 2, Variations, complete
There is only one 
before the chord at the beginning of the 2nd half of the bar in AsI and A, a to the bottom note (the b2 semiquaver). What is more, in A the accidental was written inaccurately, above the semiquaver, as a result of which GE1 assigned it to d3. Both missing naturals were added in the stage of proofreading of that edition. Chopin's patent oversight was corrected right away in GE1, hence all editions contain the right text (the fact that the to d3 was printed first is evidenced by the arrangement of the naturals and by the slight difference in size between the of d3 and the two remaining ones).
