"Kicked by Operator"

Players have been getting kicked from my Realm. This has just happened overnight since everything was working fine with the Realm yesterday. I went to check on the issue today by entering the world and as I was trying to join, a player who was already in got "Kicked by Operator". And then moments later the same exact thing happened to me when that player was trying to re-enter the world and I'm paying for this and there's no other operator in my Realm.

The pattern that I've noticed with this bug is whenever that certain player is entering the world, whoever is in it already gets "kicked". And then vice versa. I tried switching worlds and closing the Realm and then open it up again, but that doesn't change anything at all. My Realm would shutdown after so many players attempting to re-enter the world. It's inconsistent as well when people are being kicked because sometimes it would say being "Kicked by Operator" and also some players have told me that it's a Java error that they get.

Seen that there's a few others that have gotten the "Kicked by Operator" bug on here as well.

Please try to fix this bug as soon as possible.
