I created various back-ups of the "worlds" folder over time, did the same today to try out some of the older world saves and it turns out all of the older world saves were the same world for some reason. i overwrote the cloud save worlds with local worlds but the worlds were still all the same, same with the worlds i saved today, all gone and for some reason changed to some weird older version of the same world. Deleted them now since I didn't see a point in keeping duplicates
