    Description

      Summary:
      Chunks seem to have different variants between instances of worlds with the same seed.
      The issue appears to occur depending upon the order of chunk generation.

      Steps to Reproduce:

      1. Create a world with seed 5666300950629472484.
      2. Go to the coordinates 5 115 -121.
      3. Observe the Jungle close to this position.
      4. Make another world with the same world seed as before.
      5. Travel to the coordinates listed. (If the spawn is different between instances, teleporting works the best.)
      6. Observe the jungle close to this position with a focus on discrepancies.
      7. Repeat as many times as one likes.

      Observed Results:
      Chunks within the same seed generate differently depending upon the loading order.

      Expected Results:
      Chunks would be identical across all instances of the world seed.

      Screenshots/Videos:

      Notes:
      This behavior appears to be prevalent in both the Overworld and the Nether with no known instance occurring in the End.
