各雑学クイズゲームが終了すると、Resultsページが表示されます。約20秒後、これはゲーム中に各質問があなたの時間がなくなる前にあなたに与える時間であり、それが次の質問に進むと、Resultsページがリロードされます。次に、Highscoresページに移動すると、スコアが2回入力されています。そのため、以下のクラスで何かが台無しになってQuestionViewいますが、バグを見つけることができません。
さらに情報が必要な場合はお知らせください。よろしくお願いします！

修正：
かわった：
if(i == 10) {
endQuiz();
}
...これに：
if(i == 10) {
cdTimer.cancel();
endQuiz();
