Wow.. Sorry about that hiccup with the new quests! I guess that code, while working fine for testing where pretty much just I was using it, wasn't very well optimized for lots of people using it at once. :x
I've brought them back up and things should be smoother now (I disabled having multiple tasks per quest for now until I have a little more time on my hands and I'm not quite so exhausted). Going to keep an eye on it for a bit, though, and if it starts causing problems again I might have to take them down until tomorrow when I'll be better able to focus.
Edit: Ugggh, okay, yeah. I'm going to have to spend some more time with this tomorrow, that alone definitely didn't help. Sorryyyyy :(:(
are they only for people that have Gold Accounts?
