Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Playing a game recently, I had two Pokemon using Life Orb with the Ability Sheer Force. Both of these Pokemon took 10% each time they used a move, despite the fact that Sheer Force is supposed to negate Life Orb damage.
For some reason none of the music is working anymore. I've joined and watched at least 10 games and music has not started on any of them.
EDIT: Just confirmed that this is only a problem on Firefox. My other browsers play the music just fine.
