Guild Wars 2

I’ve had this happen 4 times now all at random time intervals. My group will be running the MK dungeon and all of a sudden all of us will be ported back to LA and the dungeon will reset. So far this has happened:

2 times after beating the MK but before getting to the chest
1 time while the MK was at 50% health
1 time while the MK says game was going on

Anyone else experiencing this?

It happened to a group I was in yesterday just after fighting the Mad King. Once we were back in LA there was only myself and one other member still in the party, and it turned out they hadn’t looted the chest yet (I had). As our party was 5 members when we killed the king, and 2 members when LA loaded, I suspect it’s related to the party/instance owner leaving the dungeon/party.
