Observed Result

• If a Stone or Cobblestone made of magma and water is pushed in with a piston and I try to move it further in another direction, the first block pushed in becomes an immovable block and I cannot push the block to the limit of the piston's extrusion.
  This is more likely to happen with dimensional movement.

Expected Result

• It is fatal for the device if a block that should be movable is not, so once the information is updated, we should eliminate the situation where a movable block is not movable!
