This hasn't always been this bad, but seems to happen every time lately.

1. Connect a PS4 controller via USB cable.
2. Use DS4Windows so that the game will play right with this controller.
3. Open Disgaea 2. Load a game.
4. Unplug the controller.

Expected: The game should handle controller changes gracefully.
Observed: The game freezes for 1-2 seconds, then crashes entirely.
