Piston vanishes when poweredwith a pulse at the same time as a piston under it.Piston vanishes when de-powered
It isn't a duplicate, notice how this is powered by a repeater. It is also a new bug in 09c.
Found this weird bug on bukkit/spigot with a friend and apparently it's also there in single player.
When powering a piston through a block with a piston beneath it, the piston either spits out the block or not (see pics & how to reproduce)
How to reproduce with redstone dust:
-open creative world
-place 1 lever with 4 redstone dust surrounding it
-place a piston with a block on top at the end of every redstone dust
(like in the picture)
-place pistons next to the blocks you just placed (like in the picture)
-flick lever
notice, this is coordinate and direction dependent (i think)How to reproduce with repeater/comparator:
-open creative world
-place 1 lever with 4 repeaters/comparators surrounding it
-steps 3,4,5 from redstone dust (but without the dust)
notice, this is only direction dependent (i think)if nothing weird happened, try it on a different spot.
oh and i couldn't find a bug-report about this.
Similarly to https://bugs.mojang.com/browse/MC-256534, I'm getting the impression that experimental items shouldn't be obtainable in non-experimental worlds. However, the following command gives you a shulker box with a bamboo block inside, even if 1.20 features are disabled:
{{/give @p minecraft:shulker_box{BlockEntityTag:{Items:[
{Slot:0b,id:"minecraft:bamboo_block",Count:1b}]}}}}
It is also still possible to import experimental items "indirectly" using saved hotbars:
- Open a world with 1.20 features enabled.
- Grab a shulker box and a bamboo block.
- Put the bamboo block in the shulker box.
- Break the shulker box and save it to your saved hotbars.
- Open a world with 1.20 features disabled.
- Grab the shulker box from your saved hotbars and place it.
- See how the bamboo block is inside, free to move around.
I'm guessing instead of shulker boxes one can also use chests with NBT data, armour stands with NBT data and so on.
In multiplayer contexts, malicious players can create experimental items this way, making it potentially impossible to upgrade the world to future versions of the game.

Don't know if you guys knew this, but when you use BungeeCord this problem doesn't occur
Yes, the bug is still prevalent in Minecraft version 1.8.1 Prerelease 3. I added it to the list of affected versions.
Guess this can be closed then, my bad!
