I know the schedule for maintenance can change without notice but what I want to know is that now that the maintenance started 4 hrs earlier for us(supposed to be 4PM but it already started before 12:00 noon) Would it be possible that it will not reach 8PM later?

Also I'm stretching this but I guess the plunder that I was doing before I got kicked out of the game is already wasted, right? there goes a plunder book -_-
