hello to everybody,

this is just a simple scene:
two cylinders on a groundplane;
first cylinder has an opaque green material and the second has a sss-wizard-presetmaterial (acrylic signal) applied;
the groundplane has a simple lightgrey opaque material applied, but has also the shadow checked and is set to hidden to camera;

when i start rendering, caustics will become visible on this groundplane, which is hidden to camera!?!

is it a bug?

I confirm with Multilight.
Without Multilight, it works. Confirm?
