A few players have reported their character moving or drilling on its own. This patch fixes that and adds two settings in case it ever happens again.
Fixes
An unused controller can no longer move your character while you play on keyboard and mouse. A stick sitting on the desk or slightly off-centre is ignored. Push the stick properly and the game switches to the controller as normal.
Fixed some keyboards being read as a controller and moving the player with no input.
Reset to Defaults on the Gamepad tab now resets the new settings below as well as your button bindings.
New settings (Options > Gamepad)
Controller Input: turn this off to use keyboard and mouse only. The game ignores all controllers, and button prompts stay on keyboard.
Stick Deadzone: how far you need to push the stick before your character moves. The default is now 20%, up from 12.5%. Raise it if your stick moves you on its own.
Stick drift detection
If you're playing on a controller and a stick rests off-centre for a few seconds, the game raises the deadzone to cover it and shows a message. You can change it back any time in Options > Gamepad.
Thanks to everyone who reported this. If your character still moves on its own, please let us know which controller or keyboard you're using.
