In AI there are no naturals before the 4th and 12th semiquavers (in both hands). The signs in the 1st half of the bar are of cautionary significance, yet in the 2nd half of the bar they are necessary. Moreover, the 
lowering d
1 to d1 was omitted. All the aforementioned signs appear in FE (→GE,EE).
