Simulations are closed, the real world is open. Weird things happen in the real world. They happen all the time and we expect them to happen and hardly notice when they do. Simulations approximate the model that humans use to reason about the world, but we just ignore all the oddness and can't articulate the oddness until it's made explicit by some failure.
