At first I wondered "who the hell is Stage Managing this show, and why are they letting this happen", but... seriously, I would hate to be in their shoes; I imagine they are under a ton of pressure, and this show sounds like an absolute frigging *nightmare* to have to be in charge of come show night. I mean, the very, very few times in my career that I've had to come on the God mike and speak directly to the audience... I've generally already had a conniption fit in the booth. That sounds like every night for this poor person.
Still though... actor safety comes first. Either the SM's hands are tied (with such a high profile director, you never know...), or... well, who knows. I'd love a peek into the backstage area though.
