Redstone torches stay floating when the block that it is attached to is destroyed. This happens for me when the torch is on the side of a block. This seems to just be a simple block update bug.
What I expected to happen was:
I expected the redstone torch to 'pop' off of the block that it was attached to when the block was destroyed
What actually happened was:
The redstone torch stayed floating in the air air
Steps to Reproduce:
1.Place any block down that a redstone torch can be attached to
2.Place a redstone torch on the side of that block
3.Destroy the block that the torch is attached to
