Something wrong with Y!Groups about HP?

[orionis13]

Good night!

Just 30 minutes ago -as of 20/08/07 at 12.50 am (ET) - most of my
Harry Potter-related YahooGroups disappeared! I was a member of more
than 10 HP Y!G, and now I have only 4. It's weird that the groups that
disappeared were about Harry Potter!

Anyone knows something? 

I apologized in advance, if this has happened or has been addressed
before but it just caught me by surprise since I was browsing through
one of them and got an error code (9997) and when I went to "my
groups" found only 11 groups out of the 27 I was a member of!

I'm seriously freaking out.
