When working with a super furnace smelter machine that uses pistons to rotate the machine. I saw noticed that the blocks and their lighting/texture stopped working. When I 1st saw it I tried breaking it ;when the furnaces gave texture particles like the dirt block that says UPDATE, when I restarted Minecraft the furnaces came back. Taking a closer inspection you can stand on the blocks. You cannot click/click sneak to place blocks on them. They can't be interacted with and unmovable with a piston. They can't be clicked on. When they click mined or hit  affects the block that would be affected if that block wasn't there, like the block behind them. Entering or exiting the world doesn't change.
