Looks like a person or a computer switched to the wrong program. And due to time, they can't back it up and fix it. Once the error is made, it can't be undone. They just keep on trucking.
That's a shame it happened though.
I was watching something one time--and though I can't figure out HOW they made the mistake, the show was on, went to commercial, came back but was several scenes ahead of where it should be, went to commercial on time, then it went to the scenes that had been skipped.
I'm picturing a master control operator trying to manually fix what would become a timing error...but it really messed up the program.
I've also witnessed a program being fast forwarded/rewound.
