I won't have time to update the walkthrough for this update, but here some clues on how you can progress the new content:
For Nyra's scene: you have to talk to her and after she agrees to cook for the tribe Fuck 3 of the 4 women next to the fire when she is cooking. After that ask for a second bowl of soup.

For Liandra: After completing Frisha's content with Dave listen again to Dave talking to his father in the morning/afternoon.
For Yasmine:
To see the new scene you must have had sex with Yasmine 5 times and her corruption has to be 6+ then when having sex with her change position until Giron walks in on you. You can then satisfy her or leave without fucking her again (she will then take the next best cock to satisfy herself.. Only in ntr on mode)

For Julia:
To see the new part with Julia you have to complete her previous content and then complete John's quest up to the point where Julia came in to serve tea.

After that you can talk to her in the kitchen again to start a new quest around her
(important: if you told her to improve with the butler you have to watch her while not disguised and then overstay so you get punished, after that you can confront her in the kitchen)

Everything after that should be explained in the questlog.
I've also added an animation for the scene when she licks Yasmine in the livingroom .
