I think you misread my comment. I'm not saying that I don't want to
take this series before soft freeze. I'm reminding everyone that we're
getting close to soft freeze so we need to get this merged ASAP.
After the Christmas break, we'll have less than two weeks before soft
freeze. That's not a tremendous amount of time to work out issues...

Do you think this would cause the behavior I've seen? Not clear to me.
