I was playing a match in the Museum going from the Exhibition room to the Monolith when my partner finished the map by neutralizing the Cafe. I got the message that the Cafe:Neutralized, but the game didn't end. Time kept ticking and the ND inicator which had read 1/2 now read 0/2. So I decided to kill myself. Unsuccessful, I tried jumping off of the spawn area shooting mines. No luck.
My partner was out in the Loading Screen because it notified him that we'd won. Anyways, I decided to wait for time to run out rather then leave. 7 minutes later time runs out and (of course) nothing happens. I'm still running around the level with no end in sight so I finally decide to quit session.
As it turns out I got a 100 point penalty. Has anyone had an experience like this one? What do I do next time?
