      The bug

      When an item frame is somewhere in the loaded parts of the world, the following error message appears in the server console:

      As a result, the item frame that was about to be loaded will disappear.

      When the client tries to place an item frame, the following error message will appear in the server console:

      Original description

      When updating the server to the latest 1.14.3 pre-release 3, at first start up the server console spams a lot of errors. After restart these errors are gone, but when logging on to the server, all item frames are gone.

      Reproduce: put in latest world backup with item frames, then start server again. This will give multiple errors. When restarting there are no errors and all item frames are gone.

      Also tested without datapacks, but still same issue

      Client side: when placing item frame, the client crashes. This causes error on the server, but server remains running.

      Client crash report included in attachments.
