He'll probably put them in later, according to his posts.
I think the issue was that Clara being as hesitant as she is to do anything with the MC, fucking anyone after a 10-minute makeout session with no buildup and no stat checks on her doing it, felt off. And you can see it in this thread and comments from slow burn. You could MAYBE argue she'd bang Chaz if the MC had been open with her a lot before the party, but Sebastian? That dialog had her literally selling her virginity for $100. It made little sense, and that is saying something in this game. Her stats even enter into it, where if MC has kept her lust low, she will turn down Gordon even if the MC sits there and does nothing.
There were only three options for her losing her virginity that made sense going in to the party, Gordon, the ex that she still isn't over; the MC -- her current BF; and Jackson, the guy who has been working on her behind the scenes (to what degree, differs based on routes.).
This version, even if it has fewer scenes with her getting fucked, has more animations, an actual seduction from Gordon, and a more believable (barely) reason the MC would fuck Mavis when in the hotel room. I still say that the bigger problem is that the party was so big; he should have cut the bus groping and mechanic scenes because nothing new happened there. Or he should have spent two months on the update; he kind of did now, but that was also while working on 0.16.
New version is far from perfect, then again, so is the game. But it's better than what was there before.
