Did you use QGC? There is a very recent fix, mavlink/qgroundcontrol#4242, do you have this?

I was using daily @d1cc23

I haven't been able to reproduce this so will close it. It must have been due to an early device power off or something.

Your QGC version is before the merge of 4242, so that would explain it as well.
