In Telepath Tactics Liberated on Steam Deck with the Xbox Controller layout, pressing "B" to close a character's personal inventory from the Manage Supplies screen incorrectly shifts controller input to the underlying UI layer while leaving the Supplies screen open. Switching to mouse and keyboard works around this but introduces a separate bug where gamepad cursor movement gravitates toward the last touched screen point, and the issue is specific to Liberated, not Together in Battle.
