This was mentioned on Discord, but nobody reported it here.
To reproduce issue:
  1. Go to https://homestuck.com/009300
  2. Click the next page links, eventually bringing you to 009305 (shes8ack)
  3. Press the browser's back button a few times
The page number in the url will decrement, but the actual loaded page will still be shes8ack. After a few presses, you may get redirected to a 404 page, but again, it's still just shes8ack.
