don't think it's a bug tho, i went from preious save and got all those scenes just fine; waifu started bk4 love route all new and p much the same, nothing majorly bad.
maybe the ones who don't get certain scenes kind of "missed" a step very early on, has to be the "really really omg pedo" one i guess.
aside from few typos, didn't run into anything severe bugged or flawed.
however.. the Kuvira sparring lags reeeeally bad, and when i chose the "revenge" pick in that one dialogue, that mini game wouldn't have me land a one hit. she's perma blocking, no chance to time right, too much delay on them clicks. strangely, the game fps are still constant at 60 even with the lag. must be the infamous minigame curse MiTy keeps running into..
