I use a 360 controller, on Windows 10. Before today, I could always use my mouse at the war table to join or create a game. Now when I go to the war table, I can no longer use my mouse to click on ANY of the buttons, I have to my 360 controller to 'click' on ALL of the buttons, which is really clunky.. It now takes a lot of effort and time now to search for a game or create a game.
This has only started happening today, since the new Holiday update that was released, December 13, 2016.
