Crash when loading 1.12 worlds in 1.13 - Something to do with ticking hoppers and chests?

      Whenever I attempt to load a handful of my worlds in 1.13 (which were never loaded in the snapshots, but were last saved in 1.12.x), the game crashes just before loading.

      I tried again multiple times (from backups), and optimising the world before the first load appears to be successful, but doesn't prevent the crash.

      I'm not sure what these worlds have in common, as others seem to work.

      Sorry if this is a duplicate, I couldn't find any crash bugs that sounded quite like this, but I'm not very adept at reading the crash logs.
