This is a bug - the new task, for some reason, is not being issued.
We don't know how to reproduce it and because of that we can't fix it. Do you maybe know how it is recurring?
Often starting a new game allows you to avoid this problem.
Let's try to define it step by step. Grace's quest should go through the following stages. Can you indicate at what stages you did something else and what exactly?
- You apply "Stupefy" to Grace in the courtyard
- She sits in your office. You can talk to her and Victoria
- During the conversation with Grace, there are 3 dialogue options, you need to talk about all of them - after that, a new conversation with Victoria will become available
- After talking to Victoria, she will offer to find Grace's room at the inn
- Upon entering the inn, an automatic scene is triggered where Victoria talks to Tom while we walk down the hallway to the rooms
- There are 3 doors in the hallway - two with just dialogue and one with a scene with a red-haired girl
- After we look into all three doors, a magical game is triggered to unlock the fourth room
- We enter Grace's room, where there are 3 active items
- After interacting with the board and the suitcase, we are automatically transferred to the office
- In the office, interacting with Grace triggers a dialogue with options to "persuade" and "threaten"
