Smokescreen doesn't affect party

Describe the problem. Be as specific as possible!:
Today, during a zak duo with a guildie, he mentioned smokescreen not working for him, I waited till it cooled down and tried it again, turns out it is broken.
It was working before the CvP patch, don't remember if it was between CvP and any of the bugfix patches after it(if there were any, I don't really keep track of bug fix patches, lol).
