The missing d1 minim in AF could be considered Chopin's hesitation: in AI it seems that the note was added to the g1-b1 third. It is also included in GE, based on [AG], which may be later. However, in analogous b. 120 a respective note is present in all sources, which may point towards the composer's oversight in the discussed place.
