Affects Version/s: 1.16.1
Fix Version/s: None
Before 1.16, this did not occur.
As shown in the video attached, when thd sticky piston in the following mechanism retracts, any sand/gravel on top of the block directly attached to the sticky piston will break.
When the sticky piston retracts, Sand2 will break.
This only seems to occur for sticky pistons.
