Hey Drews,
Unfortunately, if you carried your save file and the persistent file over, but there's gallery stuff missing, you'll have to redo those scenes either by redoing them or making a new save file. If doing via new save I'd recommend skipping text and zooming through.
We have lewd sounds and a voice scene in a dream and another scene with lewd sounds, which is also a dream. We look at and discuss sounds in the game every so often but its not a top priority for the game right now.
Naomis nipples used to be different colour due to lore reasons (Her witch blood/magic) but it confused people so it was changed at some point so you'll see old scenes with her original colour!
