So I got as far as stealing the sapphire and overloading all 4 circuits, but when I go to retrieve the sapphire, I can't move Nancy into the little room it's in. I've tried all the keys, but Nancy just won't enter the room, as if she's hitting an invisible wall. I've tried leaving and re-entering the room and exiting and restarting the game. I'd rather not reinstall it, go through everything all over again and get to that point just to find out it's a permanent glitch, so instead, if anyone would be kind enough to send me a saved game from right after Nancy gets the sapphire, I would be really grateful!
