      Entities randomly appear/disappear on multiplayer server between reconnections.

      Meanwhile the server constantly shows warnings similar to these:

      [13:40:38] [Server thread/WARN]: Keeping entity minecraft:chicken that already exists with UUID 329fecbe-624c-47b1-8c1c-f3b0531771e5
      [13:40:38] [Server thread/WARN]: Keeping entity minecraft:villager that already exists with UUID e901c66d-0a68-4a40-98d5-27459404b081

       

      Steps to reproduce:

      • find a village, e.g. at (-459; 77; -925) position on seed 5000000123456
      • summon 70 chicken
      • summon 20 villager
      • disconnect
      • reconnect

      After this the result is random.

      • only 1 or 2 villagers/chickens are present
      • none of the animals and/or villagers are present
      • all entities are present
      • all entities are duplicated (even my horse with diamond armor)
      • etc.

      Look at this animated gif:

      I tested it with more seeds and more animals, and results were the same.

      I also tested with previous versions, and 19w07a was still NOT affected!

      I tried to reproduce it in single player mode, but I couldn't.
