Pretty much every large update has always had unforeseen bugs ->maintenance.
Sure, its not ideal that this happens, but maybe we should try not to go complete mad about it. The guys are fixing things, or at the very least compensating for it.
I think we all know this shouldn´t happen, but hey, i´ve seen worse games.
If anything, it makes my anticipation for the event that much higher knowing that the update has less of chance to mess things up.
Lets try and think positive guys (or girls).
