When using the Optimize World option to convert my 1.12 world to 1.13, chest items are not in their original inventory slots. This appears randomly and doesn't affect every chest. I have noticed this in chunks that would have been initialized in numerous game versions.
The greater issue: some items are disappearing entirely from chests. I have only noticed missing items in a room of chests near spawn (chunk would have been created in 1.7.10). Attached are 1.12/1.13 images showing the behavior.
Environment
1.13 world converted through client Optimize World option:
* Runs as a server on a dedicated machine.
* Version progression: 1.7.10 => 1.8.1 => 1.8.8 => 1.9 => 1.9.2 => 1.9.4 => 1.10.2 => 1.11 => 1.11.2 => 1.12 => 1.13
* Seed: [-2872455129626351985]
* OS: Windows 10 (1803)
* Java: Java(TM) SE Runtime Environment (build 1.8.0_131-b11)

Oops. And MC-134115.
I'm confused why this is closed as a duplicate. The linked issue does not mention MISSING items.
