There's a bug where a player get stuck on the listen in on conversation when a new area is loaded. Like when taking the lifeboat from the ship in the start, when the beach map load in the player can't move the character and the ear icon is shown on the portrait. The only way to fix it is to load that save, or save and then load again.
That save-load seems to be the best way to overcome a lot of the many bugs with the game. Yes.. There's many bugs with the game that need fixing, but right now I can only remember that one. I'll report more when I come across them.
