This is what I have come to call the “black gremlin”. A rare bug, the source of which I have never been able to find. Sincerely sorry. The best I can suggest, if you haven't already, is to try the game on another web browser. In general this method works.
Thank you for your reply. I'll try this method. But otherwise, this game is fantastic. I'm thankful you replied, and I thank you for the amazing experience with this game, even if I couldn't experience all of it
