The other day, I saw an off-topic post and voted to close it, even though I'm still at 101 rep on the main site. Didn't think much of it until today when I was on another public beta SE site where I also had 101 rep and was unable to vote to close a question.
If you compare the faq on mechanics with the one here, you'll see the values are different. I assume it's a bug, but feel free to correct me if I'm wrong.
I'm going to miss my close hammer....
