Проблема в том, что у меня 2 сервера и синхронизация игроков происходит только после рестарта второго сервера, до тех пор, игрок не находится в вайтлисте на том сервере (MySQL привязана правильно)

Whoa cool!
I finally found an plugin supports 1.12 and MySQL
That helped me a lot!

Cool plugin! I've been using it for a couple of days now and it works great! Thanks to the developer!
