Sometimes Player1 starts automatically rolling in one direction when playing co-op on PC. You can move freely and all but as soon as the roll refreshes the charachter rolls by itself and often into the void what really annoys me. It just keeps rolling even when nobody is touching the controller. Sometimes opening inventory, pausing and spamming random buttons help but it comes back soon and it's really annoying. Player2 has no problems though and we're using the same controller.
