Seems like some major glitch on FB. When I logged in yesterday, my entire friends list was wiped. No response to my report submitted through the help center yesterday, except the standard auto-reply. Looks like there are quite a few people who have disappearing data and there seems to be no acknowledgement of the issue on the FB side.
