I had a problem with my mysql database recently, but all data from server times stayed, so I searched a command to create back a new mysql file while adding all local times of servers to it, I also tried to remove the old mysql file, but the new file appear empty. How could I do?

Do you still have the data.yml? If so, you can run /ar sync to sync the MySQL database with your local data.yml

You saves my life U_u It works

No problemo! Glad I could help!
