Please explain the relationship of updates, to a current World in a Realm game. Do updates revert the World that properly worked to a backed up version from the list found by clicking the Backups button, in Realm settings! I have recently noticed, in my purchased Realm, the Backups button. I see there, a list of files, for the current loaded World. I see an narrative statement that the backups do not contain packs. And that one may need to restore the pack. Thus, my current perception is that the inherent process, underlying that Backups button, is the culprit for wreaking havoc on previous, properly working games in a Realm, after updates happen.  I buy Worlds and Mash-Ups at the Minecraft Store because of the Resource and Behavior Packs! I do not remove them from Worlds, created from any of items I purchase. See YouTube video https://youtu.be/GZU5G-BJh2Y Shorter videos attached.
