Bug Report ID: #783160092

Just finished campaign. When starting a map and entering a portal as part of the "A Call to Arms" quest, the game exits to the login screen. No issues with the game before that. I can still play all other aspects of the game except when entering a map. I'm now stuck and can't proceed to the endgame.
