The above fixes have not worked for me, I log out, back in...still the same instance every single time.
I can confirm that this approach does indeed work, which would indicate that the problems related to many people being in the same area at the same time Zeni claimed to have fixed are still there. I know that such odd hours aren't an option for many people, but if you can, try completing the quest also before noon, as that's usually when there aren't too many people around. That's how I eventually managed to do it, I was playing around noon on a Saturday, but I'd guess any other day would do as well.Sorry to say but if you want to do this quest upon entering the first time do as I did and just log on between 2-4 AM works fine when there isnt more than 1 person in the building
This entire game is filled with quest like this. Where if more than just you are there is FUBAR. And its been like this forever or at least since my first beta invite.
The thing I find most amusing about it however is people that played the closed beta all saying that it worked just fine on the PTS. Duh 6 players vs 6 thousand
