There is no way to finish this quest with the amount of people stuck on it. Its been 3 days for me and likely many more days for others. Please devs at least acknowledge youre aware of this other than the generic copy and paste emails that tell you to check these forums. It totally stops all progress in the aldmeri dominion quest line. Maybe someone could make a thread for people who are also stuck on this? Maybe we as a community could band together and coordinate a way to get around the "too many people are in this area and so the enemies get spawn killed re bugging the quest" bug. The other alternative iws waitng possibly a month or so until the next patch assuming the devs put this on the list of things to get patched.
