I've been leveling my monk with quest bot, and it works really well. From time to time I have to click start again due to some error I get with QuestBehavior. Natfoth has been trying to fix it, and maybe he thought he got it fixed in .487, but sadly it still happens to my monk. I'm alliance, using kick's quest profiles, and I am level 45. It's nothing major though, because I babysit my bot anyway, even if it was working 100%. So, I just click start again and it starts right back up and runs for an hour or so -- I've never really timed it -- and sometimes it will stop, other times it will keep on going. Other than that, it seems to work just fine.
