About Rachel progress. Yes, its bugged. But you can skip this step
1) In game go to the map.
2) Alt-tab game and press Win+S, enter the "regedit" without quotes, open register.
3) Find page YOUR PC\HKEY_CURRENT_USER\Software\KsTgames\The Twist.
4) Now you need the line "_rachelq_h3632528058". Open this and change up decimal value on 1 score, at me it was from 13 to 14.
Now visit Rachel, click "Stay here" and take a continue.
And helpful for 0.19:
"_billyjan_h1663851949" - Billy on the beach looking for Janice
"_juloutfitscr_h966353854" - Sister outfits scores
Sorry for bad eng
