When running Deadlock as Administrator while using a controller the cursors and menu button stop working while in the shop menu. Every other button works except those ones. Also, you can only open the shop menu using the controller (short press the menu button), not the actual game menu (long press the menu button). However, all buttons and controls work as intended outside of the shop menu including button combinations. This is on an Xbox controller and the menu button is the one with the 3 parallel lines.
