Something is going on. I am in game and lagging something fierce, just got disconnected then reconnected from “blizzard services”, and everyone is running in place. I can’t do the superbloom or loot the seed bloom from one of those dreamseeds. Retail Mannoroth. Open world and emerald dream. Mid Atlantic East Coast area for connection purposes.
So, yeah, something is up for some of us anyway. I could not even interact with the menu to quit game. Had to close window to escape.
There is a player thread on the Tech Support forum too. That is most likely where updates will be, or the Twitter CS feed and/or launcher.
