Flying machines are destroyed after a restart #9220

Open Foorcee opened 1 year ago

Expected behavior

When saving the world, running flying machines are saved correctly. After the world is loaded, the flying machines continue their movement.

Observed/Actual behavior

When saving or loading the world, it happens that the constructions are torn apart or do not continue their movement. It has also been reported that they have duplicated. We have not been able to reproduce this so far.

It is observed after the update from 1.19.2 to 1.19.4.

Steps/models to reproduce

@kennytv Has a server with a world to reproduce.

Steps to reproduce:

  1. Start server and enter.
  2. Activate flying machines via noteblocks.
  3. Leave server
  4. Restart server
  5. Enter server again

Expectations: After 5: Flying machines continue their movement.

Could you provide the world or a schematic of the machine for easier reproduction/testing?

Warriorrrr commented 1 year ago

I can reproduce the issue pretty reliably but only for the most western flying machine weirdly enough. The issue where they stop in mid air was also reproducible on vanilla.
