Same as in bar 44, the raising g2 to g2 was moved from before the 2nd quaver in front of the first one in the proofreading of FE2 (→EE), most probably by Chopin. The sign was moved also in GE1, which is most probably a right revision of the editor (in the subsequent GE, the before the 2nd quaver was unnecessarily returned).
