Oh, it's a bug.
We found the reason for the error and will fix it in the next update. In the meantime, load game BEFORE catch the Grace and do not talk with Grace on chair. Ask her the first time you open a dialog and after that speak witch Victoria.
The problem occurs if you talk to Grace twice. After you catch Grace and move to the office, the dialogue with her will start automatically - ask her in this dialogue. After you've asked about everything, you'll have the opportunity to talk to Victoria. Don't talk to Grace anymore.
