This bug is also exists for java, but it never was fixed. (ex: 0 durability on zombified piglin’s golden swords). Did you tried to use the tool once for it to break?

If you read bug report guidelines on official mc site, it says mojang will not review reports that related to loss of connection to the servers.

The player is teleporting ~30 blocks up. There is no command blocks that may teleport the player up, same as teleporting down. That bug happened to me in older maps that I made. Also there is no movement on my client side second account.
