where did my dA comments go?!

I just answered a comment from my dA inbox, but the reply never showed on the page, nor did the original comment. And all others have vanished too. Not just on that piece, but on others too. I don't get a ton of comments on dA (only fair I suppose, since I don't post that many there either), but many of my art pieces had a couple of comments and now they're all gone. I filed a support ticket, but I'm wondering whether it's just me or some general glitch, because looking at a couple of deviations from my favorites, which I was sure had comments, now don't show any either.

I hope they aren't gone permanently because with dA comments I don't get any email notifications, so I don't even have copies.
