graycontrast: I'm near the end of SQ6 and I am not able to use the brain elevator. Clicking the hand Icon on the button moves Roger over to it but the lift will not move. Also on the same screen part of the walkway from the landing zone to the brain is invisible.

EDIT: I was able to figure out what happened. You should first cut your way down using the fingernail. I was somehow able to walk out-of-bounds and get down to the elevator. I reloaded a past save and got there the intended way. the elevator worked.
