Me and my friend does have a burlap sack issue, if I take the burlap sack on my head and takes it of again then I can't take on any headwear. If I log out and log in again it is still there and then I got two Burlap sacks, and that way I can log in take it of log out and in again and get infitive with burlap sacks. This also happens with my friend, it only fixed after I died.
