Is it the initial tutorial popup for restore cells? If so, could you let me know which device and browser you're using? That will help me reproduce the issue. Thanks for reporting it!
Thanks for the info! I tested the restore cell popup on several Windows devices using Chrome, but unfortunately couldn't reproduce the issue on my end. It's possible that a browser extension or setting might be interfering. Worth checking just in case.
I'm sorry you're running into this. If possible, I'd recommend trying Serenitrove in Firefox on your Windows PC. It's the browser the game runs best on, and might help avoid the issue entirely.
Let me know if the problem persists!
