Landed Falling Block does not trigger redstone updates for block entities (Command Blocks, ...)

When for example a command block as FallingSand falls next to a block providing a redstone signal, it won't update.

Example command

/summon falling_block ~ ~2 ~ {Block:stone,Time:1,Passengers:[{id:"falling_block",Block:redstone_block,Time:1,Passengers:[{id:"falling_block",Block:command_block,TileEntityData:{Command:"say Test"},Time:1}]}]}

When you place a block next to it, it will say "Test".

Note: It appears that this only affects block entities. Here are some examples:

Affected blocks:

  • Dispenser

  • Dropper

  • Command block

Unaffected blocks:

  • Rails (Activator and golden)

  • Redstone lamp

  • Piston

Fallingsand is an entity, it doesn't conduct anything.

He means when it lands and solidifies into an actual command block, the redstone doesn't power it until you give it a block update.

Confirmed for 1.12 pre-3.

For the example command in the bugpost to work now, it should be updated to:

summon falling_block ~ ~2 ~ {Block:stone,Time:1,Passengers:[{id:"falling_block",Block:redstone_block,Time:1,Passengers:[{id:"falling_block",Block:command_block,TileEntityData:{Command:"say Test"},Time:1}]}]}
