Dialogue bug - cannot progress

So I've just gotten to the part where we've been driven up to the mansion by Officer Bradley. When it engages dialogue with him after the cutscene, I am unable to choose any of the options to progress the dialogue. I click and nothing happens. Any idea why this happens and how to fix it?

In certain instances, mouse clicks are no longer registered by the game and the developer is aware of this issue.
This issue can be resolved by reloading the save file or by continuing playing with a game controller.
