title: Selenium click() function (seemingly) randomly doesn't click the box [No errors][Python]
body: <p>I am new to selenium and am making a bot to automatically do trivia. The login works great, and so do most of the clicking boxes and going to the next question.</p>
  
  <p>Randomly they do not click the button, and also do not click for the next loop. This happens a lot towards the final questions (9 and over) but this could be coincidence.</p>
  
  <p><strong>The very confusing this is that there is no error shown?
  The code finishes without errors</strong></p>
  
  <p>Does anyone have any idea of why this is happening?</p>
  
  <p><strong>Main Code</strong></p>
