A couple proximity bugs

It is really annoying me that even when an on/off switch is off, proximity still feeds through it, and even more annoying, is that proximity does not detect any emitted objects.
@grazer, I’m not sure if you are aware of these bugs, but you can test them yourself, here. http://flowlab.io/game/play/490587?v=2

Ikr?

Proximity detection works now, but I cannot reproduce the off switch not working properly.
