Andrew's safe. Many players have tried to geuss the combonation. None have succeded. (There have have been people getting in via tp+ but thats cheating in my books.) However, as you probobly know, new sg arenas were introduced recently, one of witch (arena 2) is a destroyed ECC spawn area. Andrews safe is parcially damaged, but most of the redstone remains intact. Me, I've looked. I'm not good with redstone. No idea what it could be, But if a redstone geinus were to look at it, maybe they could get a few didgts figured out. YOUR TURN. if you are good with redstone, take a look. post your findings below. Good luck.
I am guessing that he has that /credstone flag turned off intentionally. I thought about implementing a redstone combination lock like that one for my second labyrinth event, but I decided that since redstone locks are not very secure, a Lift Down sign locked via /cpassword would be a FAR better choice. I was paranoid about security, and I decided the novelty of a redstone lock would not be worth the high vulnerability that comes with it.
It's in his mansion @ spawn, and if you mess up the code nothing happens. The circuitry resets every time you make a mistake.
