It appears there's a bug, but I'm not sure if it's the new update or an older bug than hasn't been fixed. In the foursome scene with the harem, my Sparkle seems to be registered as the futa Sparkle, despite decidedly not being a futa. I'll update if it persists after the sex scene.
Edit: It's worth considering that I'm on the familiar path as well, so it might be that causing the issue in the sex scene.
Edit 2: Now it mentioned Panki nudging my exposed clit. This is a roller-coaster without end it seems.
Edit 3: It appears the Bimbo option is completely non-functional with the familiar path as well. Every time the model meant to display Sparkle shows up, it gives an error, and if you ignore it you just keep getting it every time afterwards. It also appears to be the entirely wrong transformation as well. It seems to show up as the femboi one, with Sparkle talking about still having their dick with Roopah as well. It does seem there's some problem with the familiar path and thinking Sparkle has a dick.
