Pillagers cause all players to disconnect from realm

I have a realm on Minecraft Bedrock. It is version 1.13.1 according to the backups section in the options of the realm.

I play on the Windows 10 version using the Xbox Live app to communicate with my friends who also play on the realm from their consoles (Xbox Ones and Mobile App).

We have noticed that the realm keeps kicking all players off whenever we try to attack pillagers. This happens sporadically. Sometimes we are able to kill the pillagers and everything is fine. Othertimes we spot pillagers, go up to hit them and it as if everything is frozen. We can move, but the pillagers do not move, and our swords do not make any noises to indicate that we have hit them. Then the realm crashes and we get the disconnect screen. This does not happen to just one person, but all people who are on the realm at the time. The realm will then boot up from a previous backup, and if we try to attack the pillagers again, the disconnect cycle loops.

This is frustrating as we have spent numerous hours in this realm, and now are experiencing this bug in our town. This makes it hard to continue playing on the realm because there is no way of knowing if the game will crash again, or when the last time the backup occured. Sometimes the backup occured within 5 minutes, other times within 20+ minutes.
