Lack of flats returning e in the last chord in A (→FEGE1,EE3) is certainly Chopin's oversight. The accidentals were added in FED and GE2 (→GE3GE4) and EE4.

From the 2nd quaver in bar 26 in the R.H. and from the 3rd quaver in bar 27 in the L.H. there are no arpeggio marks in A until the end of bar 32. It is undoubtedly a result of Chopin's distraction. The wavy lines were added in a proofing of FE (→GE,EE), yet in FE the 1st chord in bar 29 was omitted.
