At the time of this report this is the second instance of this bug occurring. My realm save interval seemed to stop saving the game 23 hours ago. Therefore any progress made in the game is reverted back to 23 hours. 

What I expected to happen was...:
Play Minecraft and expect that the progress made is saved and I can continue where I left off.

What actually happened was...:
Logged on to my realm and find that all progress was lost and I was reverted back to my standing 23 hours ago.
