In FE, there is no accidental before the 8th semiquaver in the R.H., which requires it to be interpreted as e3. This kind of distortion of a regular, virtuoso sequence is unimaginable. Therefore, the reviser of GE was certainly right to add a before this note. However, EE did not correct this oversight, so typical of Chopin.
