The Bug
In certain scenarios where a horizontal piston is unpowered or updated to retract, if a block with gravity is on the piston, it is broken.
What I expected to happen
When the piston unpowers, the gravity block (sand) falls to the ground and lands on the floor
What instead happens
When the piston unpowers, the gravity block breaks. It happens instantly, perhaps before the block can turn into an entity.
Steps to reproduce (as shown on setup.png or variations.png)
- Place a piston
- Power the piston using a redstone wall torch above it
- Place a gravity block on the piston head (tested with sand, gravel, anvil, concrete powder)
- Break the torch
- Watch the falling block break before it can fall to the ground
Another way to reproduce (as shown in the background of setup.png)
- Place a piston
- BUD power the piston, using a redstone block for example.
- Place a gravity block on the piston head
- Break the redstone block that is BUD powering the piston
- Update the piston (by placing a block next to it, for example)
- Watch the falling block break before it can fall to the ground
