Bug Report on The Verchiel March quest

*potential character quest story spoiler*

I was going Sera's quest The Verchiel March.  I completed the war table expedition.  Then I was to go meet up with a friend of Red Jenny at a remote locale in Crestwood.  The game transported me there, I had the scene that let you know this was a setup, I fought the first group of baddies that come.  Then nothing. 

I ran around the area for 20 minutes, using search, looking for anythig I need to click on, but there was never anything.  Eventually I gave up and travelled out of that locale (since it's remote and inaccessible).  The 'World Map' button was not there on the map screen, so I travelled to a camp and used the map's NW area change location to get out of there (due north of the starting camp).

Now everytime I go back to Crestwood, my map does not have the 'World Map' button on it, so the only way for me to leave Crestwood is via using the area change location option by the starting camp.  I've certainly tried gaining access to the remote location from the quest, which the mini mp now shows there's an enemy for me to kill there, but I obviously cannot gain access to the area. 

Edit:  I've since read what is supposed to happen here.  What I read is there's supposed to be an audial clue telling you to come here, and then a person appears, and you get different dialogue options on how to handle the person.  This certainly never happened

The quest in my quest log is completed.  I never had any conversation with Sera afterwards, as the quest never completed normally.

Edit 2:  I have the PC version of the game.
