The missing flats returning d
(1) on the 6th semiquaver of the 2nd half of the bar in A (→GE1) is most probably Chopin's mistake. In any case, flats added in the proofreading of FE (→EE) dissipate any doubts about his final intention. Cf. bar 69.
If in bar 64 the version with harmonic accompaniment was chosen, the first or third version is to be selected here.
