Lagged out of game while in dungeon

Hello everyone! First i would just like to say that i love this game and this post is not about me wanting to whine or say i am not gonna get it.So im not sure if anyone knows the answere to this other then the Trion but i was rescently in a dungeon and my group was at the end and all of the sudden my console freezes and when i get back on I cannot get back in with the same people i was grouped with to finish the dungeon. So my
question is when the game comes out will their be a way to get back in with your group if they wait for you or will you just have to wait untill they finish it and go in again.Either way i love the game but it would be nice to be able to get back in their and finish where you left off.
