We are primarily Xbox One players. The Realm is hosted on a PC. We are using the latest Chroma Hills texture pack and our Realm file size is approaching 1G. 

We have several mob farms spread across the Realm which are not active at the same time. We are not experiencing any significant lag until this issue occurs and then it's a sudden onset of lag which has concluded with a game crash.

On July 16th, several players were on our Realm when we were all suddenly disconnected from the server. We repeatedly attempted to rejoin and received error messages that either said "unable to connect" or "failed attempting to join". 

All players quit MC and relaunched however we were still unable to join the Realm. 

Approximately 5 minutes later we were able to rejoin the Realm, however we lost an hour of time. 

This has occurred several times since this ticket was reported. It happened twice in one day and we lost an hour of time the first time. The second time we lost an hour of time and it reset us to where we should have been after the first time we were kicked.
