I have this bug a lot as well. Sometimes it happens after a cutscene and sometimes just after the last fight. The commonality in every instance is it always happens near the end of the instance. Not at the end of the instance but usually right before the last series of dialogues. Yes sometimes people are getting it after a cutscene but that is always right before the last series of cutscenes. If it helps. I decided to go back with the bulk of my characters (15ish) who never did LWS2 and I was mainly after Black Lion Keys so I was running "Tracking the Aspect Masters" over and over (I ran it about 5 times). I was booted to character select twice and always at the same point. After the last boss is killed and you have to walk over and talk to the NPC's. What happens is you walk over and everyone stands around and when it doesn't work and you get booted, nothing happens and there's a longer than normal delay and you notice that you can't do anything. No emotes, no actions, and you can't talk in local (but sometimes you can talk in guild). The thing is that every time I get to this point there's a hiccup, even when it works. Every time I get here the game stalls at the same point. Sometimes it boots me but most times it does not. Either way it's frustrating because the one other commonality in all these situations is that the disconnect also seems to happen after larger than normal scale boss fights. Hope all that helps.. This bug really REALLY sucks. I've had it happening for a seriously long time now. For the longest time I could never do the second to last HoT instance past the 1st time. I just always got disconnected after the final fight. If it's getting too problematic to figure out how to fix this could it at least be possible to have the game, somehow, checkpoint more often? If I could at least get progress after each main event and get jumped to that point it would make these issues at least hurt less.
