I was doing the (1)"Worm Down" challenge..
and I through a perfect Unholy Grenade, blasting the second worm closest to the starting point all the way over to the furthest worm.. But when the blown up worm landed he landed on that angled roof in such a way that he continued to slide forward into the other worm... and then it appears he is just continually sliding.. he wont die.. he's just sliding in the same spot, against the other worm... so now the challenge is stuck... gonna refresh now =p
