Steps to reproduce
Set up two pistons on a fast clock circuit pushing a row of blocks back and forth between them.
Clone the contraption to a new location.
Repeat step (2) until the row of blocks between the pistons get cloned as moving blocks rather than the original blocks.
Expected result
One of the following
You never get cloned moving blocks in step (3), or
The cloned moving blocks in step (3) are linked to the cloned pistons.
Actual result
The cloned moving blocks are linked to the original pistons from step one, i.e. the /clone command copies exact tile entity data instead of relative tile entity data. When you activate the original pistons, the cloned moving blocks animate, and when you break the original pistons, the cloned moving blocks revert to their parent block type.
Note
Based on the original report and world save, it might be possible to reproduce this during chunk loading rather than cloning, perhaps with moving blocks being pushed across a chunk border, but I was not able able to do so in brief testing.
Original summary
When piston pushed block isn't rendered causes stuck pushing or pull when many block while loading the world.
Original description
When piston pushed block isn't rendered when loading the world causes it stuck push and pulling block or when you traveling too far cause it will not rendered redstone is running for piston is pushing loopily.

The "stuck" blocks are known as moving blocks. Did you originally clone another build to get these moving blocks, or did it just happen on loading?
Hayden Sharpless: the purpose of a bug tracker is to collect information to help the developers understand and fix bugs, not to provide individualized follow-up support. Any workarounds provided here are done as a courtesy. Your report was resolved as a duplicate because it describes the same bug as this one. If the developers decide to fix this bug the fix will be included in a future update to the game.
For your stuck moving blocks, try breaking the piston that pushed them. If that doesn’t work you can enable cheats and use a command to replace them with air or some other block. To prevent this from happening n the future, move the build so that the piston and all blocks moved by it are in the same chunk.
Also having this issue in 1.19.20 BR after a server booted everyone. We restarted the server and a super smelter broke. Those furnaces can't be walked through but also can't be mined, it just breaks the stone around them.
