"Empty pile" block

[FinnYT]

when i picked up a bowl, it made an entity and it was made of wood because it mined very quickly with an axe. the entity was called "Empty pile" and it was really weird, what is it from?

That's usually what happens when a modded in thing no longer exists. I guess it could also happen when something gets created by a mod that doesn't exist in the first place. The game's failsave to not explode if something "doesn't exist".
