i think it's a bug but only happens with such massive mirror. very few 
people do more than 2-way mirrors that's probably it wasn't catched.

please do report the bug - it's critical.

When the system comes up, it doesn't get added back to the existing mirror but rather becomes the principal member of the mirror, using its old data. Not good.
