(What follows is purely for the sake of explaining ; the point is not to find another way to do it

Let's say I have a few playbacks running and a nice stage look.
At one point I intend to kill all that and temporarily bring only a couple of beams on, so I record my beams at full in a cue and set it to mode 3.
Everything react as expected : my mode 3 cue shuts down everything and brings my beams.
Now, if I do exactly the same except that I record another playback with a shape running on those beams (circle with no intensity, or a dimmer shape) and launch it before using my mode 3 pb :
- the mode 3 pb doesn't kill anything
- and, in the case of the circle shape, it doesn't even bring my beams on.
It simply does not work at all, actually.
V10.1
Never noticed something like that with previous versions but I still have to test it.
Thanks for your input,
Charles
