never leave without actually cutting there stuff up, because if you just leave the server to try to fix it, and if no ones around itll despawn completely and if you cant cut there body just hold Square on ps4 or X on xbox even tho it wont drop the stuff then all you would need to do is leave the area and relog and go back and all the stuff should be there only do that if you cant cut the body

make you cut there bodies up and relog then join back and you should be good to go
