Stomach scaling is universal (as in I don't change the values between scenes, only the clothing). The joints are unavoidable, sadly, due to limitations with the engine.
Dialogue randomiser might give the same line multiple times in a scene, but it shouldn't be repeating the same line multiple times in a row - I specifically coded and tested for that - so if it's glitched out let me know and I'll dig into it again.
The Gwen, Chloe and Jessica flashes have been fixed for the next version - thanks!
No new scenes for kissing or touching as the lighting on those scenes is fine for now (I'll do a full sweep once the game enters beta).
The remade Pixie scenes are technically new scenes as they were built from scratch, but you're right - the phrasing in the changelog is unnecessarily confusing. I blame it on the fact that I only had three hours sleep that night ;P
Veronica secretly loves the hugs, don't let her tell you otherwise.
Madison has probably already been hiding and peeping on you hugging Veronica. She may be feeling a little left out...
