You didn't miss anything that isn't worth waiting for. Got to run the mission twice. The second time we just explored and due to my friend disconnecting, I had to continue alone. Got down to the two level 12 knights and became tired trying to find an alternative exit. Didn't know about the ghost opening doors but then I was baked and it was the end of a lot of hours with beta. It was only there for one real reason... To flood the servers with as many players as possible and stress test the server. How many people blew off their partner or plans, just so they could visit the moon? C'mon! Own up. Lol
