I think this is a dup of 671468.. The pipeline changes in FF14 have changed the stack a little bit, but the underlying pattern is still the same. not a new issue.

There are different filters involved so I wouldn't say it's strictly a duplicate.
This is still around and is pretty high volume on 39 beta.

According to, this product was discontinued in 2012.
