I don't think that would count as a bug for them to fix. Your computer couldn't fully save the world so some parts of the world is reset. Sure this could counts as a bug since this is something that shouldn't happen, but you accidentally turned off your computer. You caused your computer to not save the world properly. Nothing wrong in the game's code caused this bug to happen. You mistakenly did something to cause the bug so this shouldn't be reported.
