The servers seem to take turns being unreliable. It'll be fine tomorrow until it decides to go wonky again. --- Why would you pay for a video game guide to tell you how bad you are when I'm willing to do it for free?
I had this problem with another Nexon game called Vindictus. I'd disconnect within 15 or less minutes in the game.
