Possible Glitch/Bug (Duel)

[Vordox]

I've been farming for a while now, and there is something about Boss Encounters(Duels) That causes DCes in mid fight.
Happened 6 times out of 6 over a course of 2 hours.

This may be a local issue for me alone, but if you do encounter this random Error 630 while doing duels, so far it helped 4 out of the 6 times with a simple restart your Modem/WIFI or Cable replugging, it can help out.

Hope it's nothing too common. =/

630 is an error associated with your network. You can try check your ping in cmd for timeout and see how many timeout popped up. This game doesn't handle network timeout very well so it can d/c you when you have several timeout popped up.
