Private Plurks Going to No One

I'm having a problem with Private plurks. It seemed to start yesterday after the clique issue was fixed.

Now I can't send private plurks to a group of friends, either one or two will get it (the same ones who'd always show up with the clique problem too if that helps) or it will send to no one.

Even worse, when I delete the plurk and try again, I get the spam comment, even though no one has received it.

Yesterday I tried to send a private plurk for nearly an hour, finally sending it just to the two friends who did show up, and then having to give up because I couldn't send to any of the others I had wanted to reach.

Before I'd send the plurk, each name would show up in the name box with the x beside their name and over the box it would show I was sending a plurk to abc, efg, hij, etc., but when I hit send, there were no names listed at the bottom of the box for people it was going to, and friends couldn't see it on their timeline.
