Wasn't anything you did. I checked the moderator logs, and it showed that Brutha had edited that thread twice. He something similar to another thread of Mounds which caused the same issues -- some kind of infinite redirect loop. I don't know if it was something he did or a glitch in VBulletin, but it's not something I've seen before.
I remembered editing Mounds thread because I was hoping to get some dialog that allows me to access the thread.
The only way how I finally accessed Mounds thread was by marking it via the "search post feature" and going to the merge dialog.
At the time "Freddy's last post" was created I didn't have any moderator rights and therefore couldn't edit it.
I'm not responsible for any of those threads not loading.
