When you power a piston with an observer that detects a block update rapidly, the piston will pop off into an item.

when you power a piston rapidly (i used a repeating command block to update an observer) the piston broke off like someone broke it and appeared as an item. attached is the circuitry i used to cause this. I wasn't able to reproduce this phenomenon, so I concluded that it is rare. The design of my farm is expandable, so theoretically if you expand it you will recreate the phenomenon again sooner. If I am able to recreate this overnight with I afk with a scaled up version of this farm in a dedicated test world, I will comment with an attached image with the result, though the item will probably have despawned. Please contact me if you have any more questions on twitter @KatevanDis472 or by email with the email I used for this account. Thanks.

P.S. I posted this like 1min after my local New Year started.

Overnight I ran a test trying to recreate this bug, but it was not successful. If you wish to try this test yourself, I have included a world download to this comment. Thanks.

I was not able to recreate it either.

i was thinking. this bug may be a result of the data packs in the world. i didnt think of them earlier. i will provide them attached to this comment. maybe one of you could try it. i am very pressed for time recently. thanks

Try it without the data packs and see if the issue persists.

i found it WITH datapacks. when i created this report i didnt think of it because i havnt used the datapacks in a few months. I was asking if some one could test it with them to see if the bug is related to the datapacks.

also, attached is a zip file of the test world i used to test the bug.

Please check if this is still an issue for you in 1.16 Release Candidate 1 or later.
