The position of an end crystal will desync on the server vs. client side when being pushed very quickly by a piston flying machine at a high tick rate.

Steps to Reproduce:

1. Place the following structure above the ground
   end_crystal_flying_machine.nbt
2. Follow instructions on the cherry sign ^{(Unfortunately the contraption does not import properly)}
3. Run the game at a high tick rate

   /tick rate 80
   

4. Activate the observer that faces east

Observed Results:

The flying machine will quickly move from its original position, appearing to leave the end crystal where it was. Rejoining the world will actually correct this issue and put the end crystal in it's correct server-side position (in front of the flying machine).

Expected Results:

The end crystal would be moved properly by the piston flying machine just as it would when playing the game at a normal tick rate of 20, and no desync would occur.
