I know this topic is pretty old already, but I'm having a similar problem. The game freezes everytime Xavier exits the room and I attempt to click on the podium. Reloading an old save (from chapter 3, I'd prefer not having to replay the game from chapter 2 or 1) doesn't seem to help.
The chain of events is this:
I place the cuckoo clock behind the plant.
I walk to the lodge foyer. A cut scene is triggered. Gabriel looks at his watch and Xavier exits the room. I attempt to click on the podium. Nothing happens. I try clicking on the exits. Nothing happens. I click on everything multiple times. Gabriel remains still. I can only interact with my inventory and my options menu.
Alternatively, I place the cuckoo clock behind the plant, I walk Gabriel to the lodge "living room". I click on the chair by the fireside. Gabriel sits down, a cut scene is triggered, he glances at his watch, Xavier walks by, and he stands up again. Again, I click on EVERYTHING in sight, but nothing happens. He simply stands there, staring blindly into the middle distance.
This seems like a game breaking bug to me. I've tried to get past this part multiple times but nothing seems to work. I'd be eternally thankful to anyone who could help me through this frustrating part of the game.
