Forge cinematics/animation help needed

I’ve created a map through forge (a re-imagining of The Pit from Halo 3). Everything looks really good, but I’m having a problem with the cinematics for the intros/outros – specifically, the animations are not showing for some reason. The Camera shot is working, but the spartans don’t show up, even with the animation object in front of it. I’ve quadruple checked that all of the info matches between the animation and the camera. It was working originally when I had the map about halfway finished, but at some point they quite working, and I can’t figure out why.

Can anyone help walk me through it?
