Anytime i join a Realm, it will disconnect me shortly after joining and will not allow me to reconnect unless i Close and then Re-Open the Realm but it will disconnect all over again once i join.

This occurs on multiple different accounts that i play on, each with their own Different Realm, also happens to other people who try to join my realms and their Realms

THESE ERRORS DO NOT AFFECT A WORLD THAT IS NOT ON A REALM.

IT ONLY AFFECTS A REALM.

This Crash will also happen if i attempt to teleport across large distances

UPDATE*

if the world does not crash, it will crash when i use Kill @e or Teleport  @e commands on a Mob that has multiple of itself being used with the command at once.

Sometimes the Teleport or Kill command will even crash the Realm if it is used on only 1 of a mob/player
