We just ran the 8 man hard mode version. At first we thought it was bugged because at some point the consoles were unusable and also encountered 4x of those hard *** mobs at a time. Here is how this was solved: 1st puzzle must be first solved by NORTH 2nd and 3rd puzzle must be solved first by SOUTH 4th puzzle must be first solved by NORTH Pen and paper were required to do it in few enough turns as to not get wrecked by 4x bug mobs. To accomplish this, map out the # of turns it takes each side to solve each layer of the puzzle, then have the side that is NOT solving first turn just enough times to where the next turn would solve it, then wait for other side to complete. Rinse, repeat.
