Spartan ops Episode 9, Ch 5 not working

I went to spartan ops, chose find a game and played all of chapter nine. When I got to chapter 5 we played through and activated the three console things, the pillar in the middle opened up and nothing happened at all. We waited for a half an hour and nothing happened and the other memebers of the team dropped out of the game and eventually i got sick of waiting and did the same thing. This has happened to me twice. Has this happened to any body else and if so any ideas why this is happening?

It happened to me the first time around as well. Second time I played it, the mission continued, and I finished it. Just a bug I guess.

Also, this may or may not affect anything: for the 3rd/final switch, don’t activate it right away, wait for it to completely appear before pressing it.
