A better idea for the "Black Box" addon
Why not make it so that every survivor who is in the dream world simply can not escape until you use the alarm clock and wake up at the end of the game, when the gate is already open? The way you updated this addon is not at all like an ultra-rare quality addon.

I'd be fine with it if it was 30 seconds or so
I'm not sure I understand what you are suggesting, but Paint Brush already prevents survivors from waking up via failed skillchecks.
