Pictured here is a definitively dead Death's Leviathan.



Pictured here is an appreciated but over-eager Joining Encounter In Progress feature.



Note the progressing timestamp at the top left corner of the image. We spent a few minutes more than those roughly 30 seconds trying to progress into the hallway, past Death's Leviathan, to no avail. Joining Encounter In Progress just kept taking us back to the boss after the boss was dead. Starting combat with the next mob was not sufficient to prevent Joining Encounter In Progress from taking us back to the very dead boss, so it wasn't possible to complete the dungeon. If it's happening here, in Vet Crypt of Hearts 1, it might be happening elsewhere, too. @ZOS_JessicaFolsom
