Cannot leave instances
You can follow your progress through your achievements. There’s a special category for Living Story, which can be used as a guideline.
I had this same problem yesterday in 2 of the Flame and Frost instances. First in the one in the NW of Wayfarer Foothills, I entered this instance after stumbling upon it, went in and couldn’t get through the first gates (I think because I hadn’t yet talked to the precurser NPC), looked around and then could not leave back through where I came in and there was no button to exit the instance like what you see when you finish a dungeon. The same thing happened when I later went to the HQ place in the Charr city, I spoke with the NPC there who gave me a quest to go with Rox. Afterwords I couldn’t go out the way I came in and there was no button to leave the instance. In both cases I had to log out to character screen, when I came back I was outside the instance again.
This is actually a problem in ALL (almost) instances. The situation is that it’s the process of having a Personal Story step active which allows you to leave any non-dungeon instance. If you enter any instance – not just living story ones – after completing Victory or Death, unless there’s an interactive door like there is in Knut Whitebear’s Loft or an out-of-bounds boundary, you have to log out to exit.
I reported this months ago, and it still hasn’t been fixed. Now that ArenaNet is making heavier usage of these instances, it’s becoming a larger problem.
Stop treating GW2 as a single story. Each Season and expansion should be their own story.
