I was just doing a lvl 4 Power Matrix HL 17 36 repair mission and after I went down, i was spawned in a room upstairs, just before stairs take you to the highest point of the map. Suddenly, after a minute or two, I got moved though, into the big control room into which you jump down. Same thing happened to the player that died a short while after me. Quite annoying as we wiped because the game moved us away. Pretty idiotic it seems, so I assume that is a bug?
