Pistons crossing over the Z origin point extend inconsistently

XMLWordPrintable

    • Unconfirmed
    • (Unassigned)

      At positions where the Z coordinate is equal to 0 (the "midpoint" of the Z axis), pistons that are pushed by other pistons in the positive Z direction (South) and into power sources, regardless of whether the sources are direct or indirect, do not extend until they are updated if they must push more than one block. This has been tested with multiple different power sources, all of which respond in the same way. ExpectedBehaviour.mp4 demonstrates the same setup as ObservedBehaviour.mp4, but a few blocks away from the chunk border. Note that a mirrored configuration facing Z=0 (with the piston pushed North) exhibits the expected behaviour.

       

      Expected Behaviour

      Pistons crossing over chunk borders where Z=0 will immediately extend if they are powered in their new location.

      Observed Behaviour

      Pistons pushed South to cross over chunk borders where Z=0 do not extend if they must push more than one block to do so.

      Tested versions: Present in 1.19.3, 1.18, 1.12.2 and 1.8.9. Not present in version 1.5.2.
