With the Red stone torches u place infrot of the door and it opens... Although yes it is Hacks if he has done it before the Game has started..
Eh, you can get into that room using airstrike items (redstone torches). You're an idiot to have not seen that.
theres is actually one very easy way he can glitch a redstone torch through the game before by holding it then it glitches to the next round nether than place it door opens he goes in =)
A hack :> I'm going to archive this, as we cant really do anything about it. I'll contact an admin about this and hopefully something can be done. I'll keep this report in mind <3
