Whenever I exit my realm after a lot of work, It doesnt save fully and I have a huge setback! This happens for everyone in the realm.

I just made a realm today (10/29/19) the day of the new update. And I was excited to play with friends on the realm and after a few hours I got off, and then got back on a few hours later and realised about an hour of work was deleted and non-existing. Even when I went to go to a backup It just put It In the same place as before, without an hour of work. As this is a new update, I couldnt find anyone else having this problem. Thank you.
