Was doing a AC-Story run earlier, and we lost someone who was offline for awhile. We kicked him, and I began searching for a 5th to replace him in Lions Arch. I quickly got someone, but when I tried to go back into the dungeon it was loading a new dungeon instead of loading the previous one that had my party members in. Haven't seen a way to rejoin them, or any NPC chat selections that will send me back in.
Is there really no way to rejoin your party in the dungeon once you leave the dungeon?
