    Description

      Many block updates that should not affect scaffolding can somehow update it. This can cause excessive lag if there is a lot of scaffolding being updated in the world. Such updates include redstone and repeaters being powered and unpowered, and liquids changing flow levels.

      Here's a quick clip of this in progress with water: https://youtu.be/idY2U20qYK8

      The same setup, but with acacia logs (which act like any other normal block): https://youtu.be/lRTJqgQ57FI

      If you scale up these tests, the lag from the scaffolding becomes more severe. This bug only seems to affect scaffolding, and the lag is both client and server side.
