This has been fixed. And I don't see the effect on the latest build.

Thanks Charles, and thanks for posting the original file. I had got to that stage, but it's quite tricky getting the reflection to match the original, particularly with a fair bit of perspective.

In this Web 2.0 world it would be quite nice to have a reflection plane option - might as well build in the graphical cliches
