[Major] Cinematic Sequencer Device bugged since Update

I got a few Maps where the Cinematic Sequencer should Autoplay on “Warmup”.
Before the Update it worked, but since that i get the Sequence like it should be if i open the Lobby as the first Person.
Everyone else who joins gets a Black Screen.

This is realy bad, so hundreds of Players coudn’t play alone on my Maps because they just saw a black Screen and take at least 1-2 or more Days a break from those Maps.
