What's with the comma 'thread' on the top ten?

[Kruelaid]

I know it's not a real thread, it's another thread with a title, but all that appears as a title is a comma and when I hit the link it takes me to one of the messageboard sections.

I've been getting it a lot.

It's a new thread that your instance of the website has just found out about via the network cache of "most recent threads", but doesn't know anything else about it (like its title). It's a relatively recent bug that I'm doing my best to squashify.

Me thinks you need more tentacles.
