it's pretty straight forward with new questlines which come with this update.
olivia: be a customer in beach bar and go to lower level to start her questline.
players won't need to wait like a fool as for miranda except one step.
i personally have encountered a bug where i need to finish the first few quests twice before i can do the rest, other than that pretty smooth.
after the questline players can spend the day in olivia's apartment.
cornelia: have get her in gas station and can't access sophie's room. then go to toilet to start her questline.
the problem with this questline is players need to do a ton of level grinding, by a ton i mean quite literally.
sophie needs to have at least lv18 to be able to deal reasonable damage to jungle monsters, and even higher if players want to kill the boss monster. one guy in discord can't beat the boss with lv28, which makes me think beating the boss requires lv30+... i strongly recommend using the mod to save time, at least for this part.
on top of the ridiculous level grind, the battle system now has enemy attack animations, which slow down the game significantly. so i pick up a new hobbit, which is holding down ctrl button during the game, ctrl can speed up attack animations just like dialogs.
the path leading to jungle boss is up, right, up, left, up, left, right, right, up, right, left, left. notice the directions here are what the arrow buttons are showing, not where they're located.
after this ridiculous boss fight, players need to fight cornelia herself. however if you can pass jungle boss, cornelia won't cause any trouble.
after the ritual, players can see cornelia cleaning living room in the morning and collecting clothes in mc's room, but neither leads to sex scene.
