FIXED CONTROLLER ISSUES!
Controller should connect immediately without any issue.

If the game is started without a controller and you decide you want to use one, go into the settings menu and select the checkbox for the controller to tell the game you are using one and it will connect in game.

If a controller is connected and you decide to not use it, unchecking the box in the setting menu will free up some CPU usage, not significant but could help with slower computers if needed.

If the checkbox is asking you to connect a controller it is because Steam doesn't see your controller.

If you do have any other controller issues, or any issues at all, please reach out with as much detail as you can provide so it can be resolved.
