Losing Personal Story progress...
I also have this problem. Sometimes when I’m on WvW or doing Personal Story I lose connection with my ISP and have to start all over again. Not to mention the random dc from the game itself. It’s really annoying and demotivating for instance in long story lines like Claw Island. For sure they need to make a fix on it. Like the sPvP tournament when you got dc in a game you come back after loading Mists and then the map you were.
