b. 156-157

composition: Op. 23, Ballade in G minor

..

In A (→FE), there is no  to the 6th quaver in b. 156 (f2). Chopin's patent inaccuracy was corrected by GE and EE.
In the main text we add cautionary flats to e1/2/3 in b. 156 and to the L.H. e1 in b. 157. Flats were added also by GE, and the one in b. 157 also by EE3.

b. 159

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

In GC and FE (→EE1) there is no flat lowering c2 to c2 in the L.H. The obvious inaccuracy was corrected in GE & EE2.

b. 161

composition: Op. 2, Variations, complete

..

As in b. 149, in the manuscripts the accidentals restoring c(1) and B (b) at the end of the bar are missing. The mistake was corrected only in FE and yet only partly by adding flats to the last demisemiquaver.

b. 164-165

composition: Op. 23, Ballade in G minor

..

In these bars, there are no flats to a1 and A in A (→FE) (the accidental to a at the end of b. 164 is not necessary due to a respective  to the L.H. chord). What is more, the remaining necessary flats were inserted only in the first half of each of these bars. Moreover, in A Chopin even deleted the  that was initially put to G in b. 165 (cf. the description of A in some Preludes, Op. 28, e.g. in F minor, No. 8). GE and EE include the version adopted by us.

composition: Op. 23, Ballade in G minor

None of the sources includes a  restoring e2 at the end of the bar. It must be Chopin's oversight – it is the most frequent mistake committed by Chopin. In this case, the likelihood of an error was additionally increased by the change of pitch of the note – initially, Chopin wrote here a2 in A – performed almost certainly due to the combination with the next bar.
