    People aren't going to download zip files of your video. That's a pretty common way of spreading malware. Just post a video to youtube. Also, you should mention the hardware specs of your machine.

    Yeah, it happens for me as well.
    This is probably due to some script modifying prefab while drawing inspector that causes re-saving of the prefab.

    It happens on non-variants also.

    If you can, submit a bug report for this one please. In my project prefab that bugs-out is pretty tightly coupled, so I can't send minimum repro without a lot of pain.

    Just upload your repro project via Help -> Report a Bug.
