The augmentation dot to F
was overlooked in the editions due to the then convention of putting such dots in a place in which the tied note represented by the dot would be, in this case under g in the tenor voice. Chopin would use this convention rather as an exception (e.g. in the middle voices in bars 30-31 and 34-35 in the Etude in E, Op. 10 No. 3); therefore, it is not surprising that this dot, so far away from the note, was overlooked.
