EE1 is lacking in the accidentals before the last semiquaver in b. 59 and the 4th note of the quintuplet in b. 60. These are patent mistakes – cf. the 
lowering d2 to d
2 in analogous b. 21 – probably committed still in [A], from which they got into EE1 through a proof copy of FE. In the very FE (→GE) Chopin not only added both flats in the last stage of proofreading, but also a cautionary 
before d3 at the end of b. 60. All 3 accidentals were also added in EE2.
The same in b. 203-204.
