I havn't seen that Glitch yet, but there was one time, I couldn't do Breakers, and another time, were I knocked the guy off a cliff, and I went with him... to my dismay, I lost the round becouse I hit the Ground First.

I had a similar glitch, except I wasn't all twitching, but I was floating in air way off the cliff and I beat my friend cuz I kept doing the hell fire thing with scorpion. And you don't die if you hit the bottom first, when two people fall off, there's a seperate animation which has both hitting at the same time. You lose if you have the least amount of health when you both die, almost like when you run out of time.
