Me and my friend have a survival server that only we use, and we've been on it for around a month. My player data randomly reset, and when I join i get the default skin. Everything in the chests is still there, but the stuff in my enderchest & inventory is gone. it probably happened when i tried to start the server whie it was still stopping and there are backups, but my latest backup is from last week and I don't want to lose 3 shulkers of iron and a ton of other stuff. Is there anything I can do?
EDIT: i forgot to add that one of our other friends joined the server and played on it aswell.
