Render mask error with invisible lights

Hi!
I found something with render mask,
its works fine, until a invisible lights passes on front of the camera angle.
It blocks the mask from rendering.

There’s a file uploaded with the problem.

Thanks

happens on maya 2015 with the official 3.0 and the nightly build 3.05

Mac os 10.9.5

Thanks

Yes, this is a known issue, we are working on it.

Thank you , It caught me by surprise, because I thought it wasn’t working, and the problem was the light. Thanks
