didn't expect this to happen

We All Know that netherite block is the movable version of obsidian so i used this in making some stuff and while i playing i randomly put tnt near netherite block connected to slime piston which is in a repeat cycle which means the netherite block was moving forward and backward alot of times, so the tnt launched and when that happened the netherite block was moving with the piston BOOM the netherite block didnt even drop its gone with the piston, watch the video in the attachment for more information
