FE is missing a natural before the penultimate note in the bar; however, the accidental is present before the previous semiquaver, d3. Therefore, it can be likely that the engraver put an accidental before the wrong note, although Chopin would also occasionally write accidentals in such an illogical manner. In GE, the 
was moved to before c3, whereas EE added the necessary without removing the one from before d3.
