The ability to override the server's region was seemingly removed, since the citadel_region_override command does not work anymore. It's a pretty negative change, since I can't play the game comfortably with my friends from other regions. Previously we could use the command to switch the region to NA to comfortably play together at split ping. Now the game defaults to one of the servers instead, giving one of us 300+ ping instead, and it's impossible to play together. I hope it's being worked on and the option is not actually removed from the game.
