WTF LiveJournal??

Something really, really weird is going on. Comments that I made last night in my previous post -- which I know I didn't dream, because they were replied to -- are now suddenly gone, as are people's replies to those comments (which I know about because I got email notices, even though they are not showing up in the post).

Did LJ lose data or something, and restore from a back-up that doesn't include the latest changes to the post? Or did I suddenly slip into an alternate universe?

Anyone else having problems like this?
