Realm will not save progress, keeps reverting at random times

My realm is not saving. There are short times when I can log out and come back to see my progress, but then another day and it will revert back to the same place.

 

This started on Thursday, August 2nd when I played for a bit in the evening, logged out, then came back and my items and levels were gone and I was at my last bed. (This is the revert point I keep returning to.) 

 

The other members on my realm are experiencing the same issue (obviously because it's the same world). They will play a bit, log out and in and it'll have saved that, but I logged in this afternoon and everything reverted to the same point as mentioned above.
