I am finding myself in a bit of a pickle here.

I have already completed the quest in Nchardak, but I didn't grab one of the control cubes on my way out. I also missed the resonance gem inside. However, I have gotten the bug that locks the door, so I can't seem to get back in.

Also missing is Revus (the silt strider guy) who sells one of the gems. So I am stuck with 3 gems.

I have tried console commands to additems and moveto NPCs but for some reason they don't work (maybe I am just inputting them wrong).

Is there anything I can do? Maybe someone can post an exact way of typing in the console commands for the control cube, or how to get Revus back?
