When you use a Piston and a Slime Block above a bamboo and turn it on, you will see the bamboo be forced to move with the Slime Block even though there are no dirt under the Bamboo, which is after moved. I'm recognizing that it happens on both Nintendo Switch(singleplay) and Win10(singleplay), and Realms. Because of this, the bamboo-collecting machine using Slime Blocks don't work.
I have no idea whether it is a issue or not, but I think it worked correctly before recent updates.
