Certain menus only block a portion of the screen (recruit tab, ingame controls, leaderboard. In some cases, a menu button won't block off its own button, allowing it to be pressed again while the menu is still up. This creates multiple of the same menus. You can tell when multiple menus are up by looking at the shadow. Also you have to close each menu individually. If you spam click a menu button too much then you will crash your game, but the menus will remain after the game restarts.
