[A little bug at Jupiter]

When I go to complete the missions at Jupiter (I saw it only at Survive) I meet a little bug. There's an apparatus which moves up and move down with loop in the central part of map. You can stand under that apparatus and when it will start to move down, you will be stuck in that apparatus. If you are in this apparatus - the enemies will not can shoot you. I hate this, because I don't like the bugs in games, it interrupts the game process. Please, fix that.
