Dementia: Did I Do That?

Didn’t I just do that? Did I? Do what?

You may forget that you mined that block. When you look back, it might be there
again.

Mined blocks can return while they are out of sight. Placed blocks may disappear and return to a random
inventory slot, while unseen nearby blocks can silently mine themselves.

Items may change slots while you are not looking or return from a chest or
barrel. An advancement may be forgotten and earned again. Even a mob you just
killed might reappear behind you.
