Before accepting the quest, Catbeard will talk about his lawyer giving you details on his escape plan. The problem is he won't say his lines of the dialogue.
There a few missing dialogues scatter across the storyline but this is one I managed to pick up and report. Good hunting.
Welcome to the message boards Cool Rebon. It is a good player that cares enough to help to improve the game. These kinds of things get missed and your quick eye is very appreciated. I am looking forward to more of your astute observations.
