so i found a false block glitch

[Kepler2258]

the false block can be pushed by a piston, pulling it results in it vanishing, i can attempt to mine it but itll never break (acts like a protected block) and only i can see it, it can be created by placing a block (in my case a diamond block) where a claim gold block will show up upon right clicking a shovel, after it does, mine the gold block, itll drop your block that you placed there, after about a minute when the gold and glowstone vanishes the block will reappear, here are the screenshots of my perspective vs my alt account perspective, i guess its just a harmless bug, i dont think there is any way to obtain it

Make a bug report, don't show it to everyone cause that's leaking glitches and is punishable
