I was playing Typing Derby alone, when the ending word was a blank word, that I could not get past. No key presses were considered incorrect, and pressing space did not let me past it.
The prompt was about aliens, with a character speaking about their dining room. The end was ‘if worst comes to worst, will kill them all",’ directly after being the impossible blank word.
EDIT: Amazingly, I played again and immediately encountered the bug again, which allowed me to record it!
Here is a link to the video, which may not be live yet, as I’m uploading it as I type this: https://youtu.be/-I6KjKDPCP4
