I do not know why this happened, I never saw reports like this before.
Most probably this is because of fastmap. I did not hear any report that
it was extensively verified WRT power cuts, and my theory is that there
is a bug in fastmap which causes this, and this may be related to power
cuts. I do not have proves, but suggest you to dig in this direction.
E.g., setup power-cut testing.
