While I was strolling around High Island with Isobel I came across Gierry Chatillon and his wife?
Both where a bit intoxicated although Gieerry was a bit more drunk than Finuya...
Anyhoo.. while I was talking to Gierry I got two dialog choices, both where red, which indicates they are vital and can't be change afterwards.

My choices:
Maybe you should stop.
You're on vacation? Why stop now?

But nothing happen, in fact I could talk to him again and select the other answer and still noting happen.. I could select any answer over and over again without anything happening..
I'm guessing the dialog selections should not be marked red...

Totally a game breaking bug... ish
