Issue with Direct Messages

As far as I can tell, I sent out all the links to the monthly picture packs -- the site's being weird and only shows the same 4 people selected for messages over and over again, even if I have totally different filter settings. But when I check my sent messages, it looks like it went to the right people? I think?

I opened a support ticket, but who knows how long that'll take or if they'll even be able to fix it. If you didn't get a message with the link and you think you should've, please let me know. Sorry for the trouble!
