A Stock/ Vanilla 1.10.2 server running on Debian Linux. Java 8 on the server.
Client on Windows 10. Java 8 also on the client.
When you are in an anvil (Possible other blocks that when you close the GUI the item drops) and you get kicked the items in the anvil disappear (Are removed from the game). I would expect the item to drop on the ground.
- Log into a multiplayer server and use an anvil (put an item in ta slot)
- Have someone else kick you off the server
→ The item in the anvil will be gone and will no longer exist
