      How to reproduce

      1. Spawn a wolf
      2. /execute as @n[type=wolf] run data modify entity @s Owner set from entity @s UUID

      The game instantly crashes and does so again every time the world is subsequently loaded.

      This happens with cats too.

      I want my pets to experience this:
