Hello,

We encountered a problem with the redstone and it's so embarrassing.

We wanted to do command blocks and we had this bugs (redstone powder flying, disincroning other redstones ...) Watch the video (1 mn 30)

This problem was detected in 1.12, I doesn't test in previous version.

The redstone can bug flying machine with redstone_block and piston extension ans slime block

• No problem of tps
• No connection bug*
• Problem appear with the clone command of the game and expand it per chunk
