Overwatch’s Lucioball mode is all fun and games until D.Va or Widowmaker shows up, and somebody loses an eye. Or a head. It’s a bizarre glitch, and Blizzard has some advice for people taking advantage of it: don’t.

What began as something of a funny prank has turned into a game-breaking exploit. Some people have figured out how to reliably make the glitch occur, and Blizzard isn’t cool with that. In a forum post, game director Jeff Kaplan explained:

“Apologies for this bug. We’ve attempted to fix it numerous times and have had unrelated issues preventing the fix. We hope to have a fix this week.”

“In the meantime, we are in discussions with our Customer Support group to start taking action against those deliberately using the bug to play heroes other than Lucio.”

“Please do not exploit this bug. Fair warning.”

So yeah, in case it wasn’t already clear, Lucioball is short for “Luci-only-oball,” which would be a very bad name for anything. Other heroes will just have to wait for their own sports, like Reinhardt Croquet, The Genji vs Tracer Ass-Olympics, and Sweaty Short-Shorts-Wearing Badminton On A Sunny Country Club Court Starring Reaper.
