Hiya,
yesterday a friend of mine mentioned that he was browsing through the data files and found a bit of dialog he's never seen in the game. It's between Count Claylan and Debutante Alicia in the Mithrest Inn. They're supposed to make out in the corner, yet when you aproach them they're just saying something like "Leave me be". He said restoring that dialogue is as simple as correcting Alicia's death variable, since everything else is in place and it's just that mismatched check preventing it.
I don't rightly know if that's the stuff for UB (being it's just a simple bug fix), but since you're out on a Quest for Restoring the Lost Dialogues , I found it somewhat fitting...
