What the code gods giveth, the code gods have had to take away...
It seems the patch that gave us the WALK power has been causing more instability with the system, therefore the game has been rolled back YET AGAIN to the previous build.
In addition, because of the instability of the servers, especially those on the West Coast, the Halloween Event has been extended ONE MORE DAY.
Daylight will return to Paragon City and the Rogue Isles after Wednesday, November 11th 11:59 PM Pacific Time (2:59 AM Eastern Time on Novbember 12th).
Sorry guys, you should blame the Rikti Monkeys for this. They're really more dangerous than you know.
Update 11/12/09: Well I'm proud to inform you that the sun has returned to Paragon City and the Rogue Isles, and people can once again WALK.
So get back out there and start STRUTTING!
