I lost all of my progress

Hallo! Recently I wanted to connect my Apple account and as a result all of my progress was deleted. It got back to an old account that I made a long time ago and had forgotten. All of my progress that I have made was gone! There was no warnings, nothing. I couldn’t also found a place where to report the issue in the app.
How can I get it back?

Hi, thank you for reaching out.

Did you connect to any other accounts besides Apple id? If you do, you can connect to the same account and retrieve your old progress.

If you didn’t, do you still remember your game id for your new progress? If you don’t, then have you updated your nickname?

You can send a mail to mars.zhu@shikudo.com for faster response.
