Thank you for letting me know!
I've tested the game on my laptop (Chrome/Edge/Firefox) and my phone (Safari), but I haven't been able to reproduce the error. Could you please tell me a little more about your environment?
1. Are you playing on a desktop/laptop (PC/Mac) or a mobile device (phone/tablet)?
2. Which browser are you using?
3. Does the issue persist if you click 'Clear Cache' on the title screen and restart the game?
