Normally we can vote on just 20 questions in the close queue, but yesterday the limit was increased to 40 questions.  Today the limit is 20 again.

Was this just a mistake?

I was hoping that it was a permanent change, as the queue grows slightly longer each day, so it can never be cleared out, which makes me sad panda.

P.S. As of now (16:39Z), I was able to vote on a 21st question.  Perhaps the limit is a moving target.
