Custom superstars are invisible in some Universe cutscenes.

[Holding These Alligators Down]

I have Penta in a rivalry with Mysterio......

Penta wins and in the cutscene Rey Mysterio leaves the ring and points at Penta all angry like because their rivalry is not finished yet.
Thing is Penta is nowhere to be seen and then the camera moves to the ring post as if someone is climbing it to celebrate but Penta is invisible.
