klappis: I failed to remove the distruptor on the transporterpad on mission six and now everytime I transport back I get squished. What should I do? My last save is several missions back.
If this is the mission where this poor guy gets melted, then that is a teleporter that will -never- be usable.
If I recall correctly, there's a different teleporter that you can use, which is also not really nearby, so it might require some backtracking on this floor.
Edit: Never mind the above, it's a different mission.
I'm not sure: Is there a keypad near the teleporter? You should be able to find the code to it nearby, and unlock the teleporter with it.
