Can you run btrfsck without --repair and capture the output and upload it somewhere so I can make sure I've restored properly. I can reproduce the problem but I'm worried that I'm reproducing it because I've restored badly and there's something else wrong, I want to make sure I'm seeing exactly what you are seeing.
