Title: Minecraft Bedrock – Shulker Box and its contents disappeared after leaving the world without saving

Description:

I was playing Minecraft Bedrock Edition and had a Shulker Box containing my items in my world.

I left the world without manually saving it. When I opened the world again later, the Shulker Box and all of the items that were inside it were gone.

Steps to reproduce:

1. Open a Minecraft Bedrock world.

2. Place a Shulker Box.

3. Put items inside the Shulker Box.

4. Leave the world without manually saving.

5. Open the same world again.

6. The Shulker Box and its contents are missing.

Expected result:

The Shulker Box and all items inside it should still be present when I return to the world.

Actual result:

The Shulker Box and all of its contents disappeared.

This caused me to lose valuable items. Please investigate whether this is a known Bedrock save/world corruption issue.
