Guild Wars 2

I was playing Twilight Arbor story mode today with a guildie as well as some others we found outside, got all the way to the second champion, when one of the members left the party or was disconnected (not sure which, as they just disappeared). All of us were then immediately kicked from the dungeon, and when we went to re-enter it, we were back at the beginning. I’m not sure if this is working as intended, I seem to recall I joined a group in progress in Ascalon Catacombs before, but it struck me as odd.

Is this a dungeon issue you are aware of?

I also experienced the same problem
