Like I said, I dunno. I don't remember what all the choices are and for what characters even. My saves starting from the beginning go back months and I just continue on when new update comes. The scene showed up for me and I have a save right before it, that is all I can say really.But we don't have a choice to make with Ada in 0.8 and the one in 0.6 is to refuse Ada?
Edit-now you can't refuse her in 0.8 if you are on harem route.At least my save from 0.6 don't give me that choice.But 0.6 game still let me refuse.Strange.
