Just going to use the replies here as a way to make a bug-report (I'm a gamedev myself so I know how important these can be.)
Helena Route specifically.
* Upon meeting Solaire for the first time and when Helena arrives.
Suddenly switched from Solaire speaking to Altea who isn't in this scene.
Solaire: "When you assaulted Lord Wolfson's castle years ago, sorceress."
Altea: "That is where you know me from."
