Situations like this mostly occur when applications that allow you to create a clone of a game that has been launched (for example, software like Parallel Space) are being used. This can also be done using a built-in functionality of Xiaomi devices called Dual Apps. Such applications can lead to the game not functioning correctly, so we don't recommend using them when you are playing. 

You should also check the stability of your internet connection, try relaunching the game, or free up some of your device's RAM. 

If you have carried out all of the above recommendations but the issue still hasn't been resolved, please contact support in one of the following ways: 

1. Select the Support Team section in the game Menu.
2. Go to the "Ask a question" form via this link.
3. Send an email to games.support@plarium.com.
