It was with one of those evlution "egg" hoppers, full of paint.
I didnt notice anything when I was chrono-ing but on my first game with it, I turned the blade on and started to play (the eye was automaticaly on). I made my bunker and began to shoot. it shot, the back block stayed out for a second, and I couldnt shoot again until it returned fully. So I paniced and started pressing buttons till the eye was off. I poped out of the bunker and got splated.
That was not to happen again, but was pretty funny at the time. A few of my team had the same problem but somehow we still won that game. I know I had nothing to do with it.
