I begin a Realm and everything was fine until the new update came out. All of sudden, every time I got off and reloaded back in, I would lose items. At first I thought a friend was stealing my items so I started a new base away from everyone during working hours. Got off for lunch and when I came back all the items in my chest disappeared. I tested it and eventually all my chest items except for seeds were deleted. In frustration I started my own solo world thinking it was a Realm issue. When I reloaded into my solo world all my items on my character were deleted but not the changes I made to the world. Played for hours since I didn't lose much progress. Stored everything in my chest and then when I reloaded at night again (in my SOLO world) all my items deleted. This has absolutely turned me off from the game since I can't be sure if I start a world I won't just lose everything all of a sudden.

Everyone is insisting that I take backups but when I load backups I spawn in the initial spawn zone, meaning if my base was across the world I would have to create a boat or turn on creative mode (which removes my achievement progress) to get back to my created base.
