Three cautionary naturals before the 3rd quaver in the bar are present in A, yet they were removed in a proofing of FE (→GE1,EE3). It seems to be Chopin's mistake, as after d1 and d2 at the end of the previous bar, the warning is quite justified in this place. The accidentals were added in subsequent GE,s and EE4 (in the latter only in the R.H.).
