Yes that is why this new function is ther because as you say the wiki is not 100% complett and far from correct with the new version
Well.....they don't even update some wrong or outdated information in the story tracker, at most they can see more correct information in the spoiler.
The most common is Meet people:
Hanna's description is after 8 days, the spoiler says that the game has been played for 8 days, so it is on the 9th day of the game, you can find her in the Gym.
Kylie's description is after 7 days, and the spoiler says that the game has been played for 6 days, so it is on the 7th day of the game, and she can be found at the university.
Lexi's description is after 7 days. In the spoiler, it is written that the game has been played for 9 days, so it is on the 10th day of the game. You can find her in the dark alley.
The description of Palla is after 10 days. The spoiler says that the game has been played for 10 days, so it is on the 11th day of the game. You can find her in the Mall.
The walkthrough is about Emma, you have to play for more than 10 days (> 10), so you can dream of her on the 11th day at the beginning of the game.
I'm not a player from an English-speaking country, so I don't know which girls' explanations above are correct. In Chinese grammar, the opening is the first day, and after 7 days means that the game has passed 7 days, so Hanna and Palla are correct.
