Ok, the first "total bitch" for male MC text is present in the arm64 version too, it occurs in the scene in Rachels room where the MC asks her to show her tits.
An additional note, something else you have probably already sorted out, in the earlier scene (first pills scene?) where Rachel shows the MC the collection of tools, a reference is made to "it's not even lunchtime..." but Rachel and Ellie have both been out (work/school I assume,) so surely this should be referring to the evening meal, not the midday meal?
Anyway thanks for your replies.
