So I was doing Tartarus on my character today (December 12, 2015), and I died. I proceeded to flee and get health and return. We were at Cerebus when this happened, and when I did the Dungeon Recall feature, I was in a different dungeon then the people I was with. I could not teleport back to them because it is restricted in that dungeon. All of the bosses had respawned, and I was in a different dungeon then the people I was just with. This is a major bug, and needs to be fixed asap. I wasted a good 2-3 hours trying to get to Hades when the game rips me off.
