On my 2nd playthrough of 0.3.1 and doing the path with Charlene. Don't remember if I got this the 1st time through but think I did. During the visit where she reveals having bought a Cosplay costume after you telling her they'd look better on her and she's about to fetch it from her hiding spot, I get a scene where she jumps up at Tony, giving him a big hug and the text 'NOT AVAILABLE IN THIS VERSION' shows. Doesn't seem to interfere with the VN and story line, clicking progresses to next scene where she's about to get the costume from her hiding spot in the closet.
If however I choose to tell her that she's prettier than the girls on those posters,the next scenes are different and that text does NOT appear.
So what is it that isn't available in this version? Can't be much since they're both still wearing their clothes in the next scene. I suspect it's the Cosplay costume since what she ends up wearing is even less fashionable than the clothes she already had on. That plus the 'thought' "Oh! How nice, I'll start with this one." implies she has more than one outfit while she just told the MC she only had the one Cosplay costume. That response actually fits much better in context if you selected to tell her she's prettier than those postergirls
This visit already feels weird, after the talk about her studies and dropping the philosophical remark, having only the option to ask about her sex life left, she reacts as if she just opened the front door, saying "Tony! You came back!" which feels totally out of place at this point.
And the English translation in this visit...[cringing]
