So, the following happened. Fractal level 7, second fractal of the round, Cliffside. We were up to the arms, and just managed to beat one of them, when the hammer bugged out and disappeared. We wiped and found it again, HOWEVER, Chanters no longer spawned on one side.
We beat the other arm as well, but when we had to beat down the last bit of health on the other one, we found ourselves trapped, because there were NO ENEMIES to charge the hammer with.
I know we were just plain screwed at this point, but for the love of Zhaitan, could you PLEASE double-check the different possibilities in these fractals?
