I need some help. Everything is gone. Restarted the server and it's all gone. No backups, had a save from before this happened but all it did was change seed. Removed "image on map" plugin because it was in an error message, nothing. Different seed. Can anyone help? I've asked Minehut on twitter but unfortunately their method didn't help so I messaged them on support (their website.) I haven't gotten a reply but does anyone have any advice?
