My island had a problem with a few of the buildings getting messed up. So, not knowing wether the backup was recent enough or not (because it no longer shows the age of your backup), I made a copy of the map. No, I made 3 copies of the map. I reset the original one, and to my surprise, the last backup I made was ages ago, when the map was in beta. So, I go to one of my backups. Then to the other. To the last one. All reset. Every single one of them. I don't care if it's a bug, or that's how it's meant to work in fortnite. That is not how copies are meant to work. It's stupid, I lost months of work, all because of the stupid glitch that appeared at the start and ruined a few bits here and there. Bullshit.
