Yes I have the same problem. I took my army to the camp, started the quest. However the first time I only got to the part where the Elven traitor starts running away. I then realised I did not have any male wardens to loot. So I returned to my town, got some wardens and came back to the quest. This time I only got the initial introduction but no further quest clues. I eliminated all enemies, and the quest does not finish. Exited quest, came back another day and tried the quest again - still no finish.
