Using my profile that was fine the night before, I spawned at the spawn point not myself without my armor, and my animals are no longer mine.

My sister and I play couch coop on her world, at approximately 3:00am central time on Wednesday July 16th, we saved and quit for the night and everything was fine. I was in my bunker with my armor on. I got on this morning and when I got on I was at the spawn point, not my character without armor. So I went home and my animals no longer belong to me. So I looked at suggestions someone said go to a previously copied world and just recopy it, you'll have to go back to that last copy but its better than nothing. So we had a previous saved copy from a week ago, I popped into that world and its the same problem, im at the spawn point with nothing of mine and my animals are not mine.
