SOS

So there’s a bug. I was building and having fun, to safe what I had built I clicked play (if my device crashes than it weirdly deletes all what I have built til the last time I was „in the world“) but it crashed. Instead of getting thrown out of the game, I got kicked to the game menu. There I got told, that the game dicided to crash and save my build under „Backup 9“ (I have a lot of backups). After that they asked If they should try to load it again when accessing the building menu, so I clicked „yes“ and this was shown to me:

No matter how often I tried to open it, that was what happened. But there was something funny, if I tried to load it, there was no cockpit, so I clicked „play“ to see what happens and the „loading level“ was up there, but nothing happened. I closed the game, opened it again and all my 9 „backups“ were gone (isn’t that bad, there only were backups from already finished builds).
So what should I do? I don’t want to build something new because I’m scared that it could happen again...sooooo......help?
