What is variable for the new Rachel content? It is way to far to start again.
For those wondering about the Rachel content in the update (I was worried I screwed something up). It's likely you don't have it because you didn't use the femdom woman to deal with Rachel's husband. You probably used intelligence way back in V0.3 so he wasn't a problem. You then likely used the femdom woman to help with the girl blackmailing Carol or getting rid of the Max dude instead. Reading through the scene, it's not really relevant to your playthrough in that regard. I'm assuming the "new character" mentioned in the walkthrough will have an alternate path to meeting them later.
For those wondering and wanting to confirm. Check your save file if sasha_event_6=1, you helped Carol be free of the sorority and that will then make sasha_event_10=1. For the Rachel scene, you'd need sasha_event_10=2 which could bork your save as several of these triggers are related.
